NOTE
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or alternately configured for electromagnetic compatibility.
WARNING: Do not place a portable radio in the area over an air bag or in the air bag deploy-ment area. Air bags inflate with great force. If a portable radio is placed in the air bag deploy-ment area and the air bag inflates, the radio may be propelled with great force and cause serious injury to occupants of vehicle.
WARNING: Turn off your Two-Way radio when you are in any area with a potentially explosive atmosphere, unless it is a radio type especially qualified for use in such areas (e.g. FM or Cenelec approved). Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even death.
WARNING: Do not replace or recharge batteries in a potentially explosive atmosphere. Con-tact sparking may occur while installing or removing batteries and cause an explosion.
WARNING: To avoid possible interference with blasting operations, turn off your radio when you are near electrical blasting caps. In a “
blasting area
” or in areas posted “
turn off two-way radio
”, obey all signs and instructions.
NOTE
The areas with potentially explosive atmospheres referred to above include fuelling areas such as: below decks on boats; fuel or chemical transfer or storage facilities; areas where the air contains chemicals or particles, such as grain, dust or metal powders; and any other area where you would normally be advised to turn off your vehicle engine. Areas with potentially explosive atmospheres are often but not always posted.
CAUTION: Do not use any portable two-way radio that has a damaged antenna. If a damaged antenna comes into contact with your skin, a minor burn can result.
CAUTION: All batteries can cause property damage and/or bodily injury such as burns if a conductive material such as jewelry, keys or beaded chains touch exposed terminals. The conductive material may complete an electrical circuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when placing it inside a pocket, purse or other container with metal objects.

Theory of Operation
2.1 Introduction
This chapter provides a detailed theory of operation for the radio components. Schematic diagrams for the circuits described in the following paragraphs are located in Chapter 4 of this manual.
2.2 Radio Power Distribution
A block diagram of the DC power distribution throughout the radio board is shown in Figure 2-1. A 7.5V battery supplies the basic radio power (UNSWB) directly to the electronic on/off control, audio power amplifier, power amplifier automatic level control (ALC), and low battery detect circuit. When the radio on/off/volume control is turned on, the switched SWB+ is applied to the various radio power regulators, antenna switch, accessories jack, and keypad/option board, and transmit LED. The Vdda output from the 3.3V Vdda regulator supplies the microprocessor with operating power. Data is then sent to the controller ASFIC to turn on a DAC which takes over the momentary-on path within 12ms. The SWB+ signal supplies power until the radio is turned off. Jumpers for configuring the Vdda and Vddd regulators are shown in Figure 2-1 and described in Table 2-1.
The radio turns off when either of the following two conditions occur:
• Radio on/off/volume control is turned off.• Low battery condition is detected.
If a low battery level is detected by the microprocessor through either of the above conditions, the radio personality data is stored to EEPROM prior to turning off.

The keypad block diagram is shown in Figure 2-2. The comparator compares the voltage when any one of the keypad row or keypad column keys is pressed. Pressing a key sends a message to the microprocessor through the output (KEY_INT) line signifying that a key has been pressed. The microprocessor then samples the Analog to Digital voltages at the keypad row and keypad column, and makes a comparison with a map table to identify the key pressed.

2.5 UHF Transmitter
The UHF transmitter consists of the following basic circuits as shown in Figure 2-4.
• Power amplifier (PA)• Antenna switch/harmonic filter• Antenna matching network• Power control integrated circuit (PCIC)
Figure 2-4. UHF Transmitter Block Diagram
2.5.1 Power Amplifier (PA)
The PA consists of two LDMOS devices:
1.
PA driver, U101
2.
PA final stage, Q110
The LDMOS driver (U101) provides 2-stage amplification using a supply voltage of 7.3V. The amplifier is capable of supplying an output power of 0.3W (U101-6 and -7) with an input signal of 2mW at 3dBm at U101-16. The current drain is typically 160mA while operating in the frequency range of 403-470MHz (Band 1) or 450-527 MHz (Band 2).
The LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W. The current drain is typically 1300mA while operating in the frequency range of 403-470MHz. The power output can be varied by changing the bias voltage.
2.5.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104 and C106) and two current limiting resistors (R101 and R170). In the transmit mode, B+ at PCIC (U102) pin 23 goes low turning on Q111 which applies a B+ bias to the antenna switch circuit to bias the diodes “on”. The shunt diode (CR102) shorts out the receiver port and the pi network. This operates as a quarter wave transmission line to transform the low impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, creating a low attenuation path between the antenna and receiver ports.

2.5.3 Harmonic Filter
The harmonic filter consists of C104, L102, C143, C103, L101, C142 and C102. The harmonic filter for UHF is a modified Zolotarev design optimized for efficiency of the power module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.
2.5.4 Antenna Matching Network
The matching network (L116 and C141) matches the antenna's impedance with the harmonic filter to optimize the performance of the transmitter and receiver.
2.5.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the PCIC (U102) to regulate the power output of the radio. The current to the final stage of the power module is supplied through R102, which provides a voltage proportional to the current drain. This voltage is then fed back to the Automatic Level Control (ALC) within the PCIC to regulate the output power of the transmitter.
The PCIC contains internal digital to analog converters (DACs) that provide a programmable control loop reference voltage. The reference voltage level is programmable through the SPI line of the PCIC.
The PCIC internal resistors, integrators, and external capacitors (C133, C134 and C135) control the transmitter rise and fall times to reduce the power splatter into adjacent channels.
2.5.6 Temperature Cut Back Circuit
Diode CR105 and associated components are part of a temperature cut back circuit. This circuit senses the printed circuit board temperature around the transmitter circuits and outputs a DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power decreases to reduce the transmitter temperature.
UHF Receiver 2-7
2.6 UHF Receiver
The UHF receiver consists of front end, back end, and automatic gain control circuits. A block diagram of the receiver is shown in Figure 2-5. Detailed descriptions of these stages are contained in the paragraphs that follow.
Figure 2-5. UHF Receiver Block Diagram
2.6.1 Receiver Front-End
The RF signal received by the antenna is applied to a low-pass filter. For UHF, the filter consists of components L101, L102, C102, C103, and C104. The filtered RF signal is passed through the antenna switch circuit consisting of two PIN diodes (CR101 and CR102) and a pi network (C106, L104, and C107). The signal is then applied to a varactor tuned filter bandpass.
The UHF bandpass filter consists of components L301, L302, C302, C303, C304, CR301, and CR302. The filter is electronically tuned by DACRx from IC 404 which supplies a control voltage to the varactor diodes (CR301 and CR302) in the filter, as determined by the microprocessor, depending on the carrier frequency. Wideband operation of the filter is achieved by shifting the bandpass filter across the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L306, L307, C313, C317, CR304 and CR305.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth of the filter is approximately 50 MHz. This enables the filters to be electronically controlled by using a single control voltage from DACRx.

2-8 UHF Receiver
The output of the post-RF amplifier filter is connected to the passive double balanced mixer consisting of components T301, T302, and CR306. Matching of the filter to the mixer is provided by C381. After mixing with the first local oscillator (LO) signal from the voltage controlled oscillator (VCO) using low side injection, the RF signal is down-converted to a 45.1 MHz IF signal.
The IF signal coming out of the mixer is transferred to the crystal filter (FL301) through a resistor pad and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and L311. The crystal filter provides the necessary selectivity and intermodulation protection.
2.6.2 Receiver Back-End
The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by components R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301, pin 3 via C330, C338 and L330 which provides the matching for the IF amplifier and U301.
The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, to produce the recovered audio at U301, pin 27. This IF IC (U301) is electronically programmable, and the amount of filtering (which is dependent on the radio channel spacing) is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in the IF IC.
The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC.
In the absence of an IF signal, the VCO searches for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO locks onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode, CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of C362, C363, C364, R320 and R321.
The IF IC also performs several other functions. It provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor, and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification.
2.6.3 Automatic Gain Control (AGC)
The front end automatic gain control circuit provides automatic reduction of gain for the front end RF amplifier via feedback. This prevents overloading of backend circuits by drawing some of the output power from the RF amplifier output. At high radio frequencies, capacitor C331 provides a low impedance path to ground for this purpose. CR308 is a PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed to turn the PIN diode on. Transistor Q315 provides this current where, upon saturation, current will flow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is an NPN transistor used for switching. Maximum current flowing through the pin is limited mainly by the resistor R319.
The radio signal strength indicator (RSSI) voltage signal is used to drive Q315 to saturation, i.e., turned on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and the input power to the radio.
The resistor network at the input to the base of Q315 is scaled to turn on Q315, activating the AGC, at certain RSSI levels. To turn on Q315, the voltage across the transistor’s base to ground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe) present at Q315. The resistor network with thermistor RT300 is capable of providing temperature compensation to the AGC

circuit, as RSSI generated by U301 is lower at cold temperatures compared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-C network used to dampen any transient instability while the AGC is turning on.
2.6.4 Frequency Generation Circuit
The frequency generation circuit, shown in Figure2-6, is composed of Fractional-N synthesizer U201 and VCO/Buffer IC U241. Designed in conjunction to maximize compatibility, the two ICs provide many of the functions that normally require additional circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the schematic to locate reference designators.
The synthesizer is powered by regulated 5V and 3.3V, which are provided by ICs U247 and U248 respectively. The 5V signal goes to U201-13 and -30 while the 3.3V signal goes to U201-5, -20, -34 and -36. The synthesizer in turn generates a superfiltered 4.5V signal to power U241.
In addition to the VCO, the synthesizer also interfaces with the logic and ASFIC circuits. Programming for the synthesizer is accomplished through the data, clock and chip select lines from the microprocessor. A 3.3V dc signal from the synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to U201, pin 10. Internally, the audio is digitized by the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going to the VCO.
Figure 2-6.
Frequency Generation Unit Block Diagram
2.7 Synthesizer
The Fractional-N Synthesizer, shown in Figure 2-7, uses a 16.8MHz crystal (FL201) to provide a reference for the system. The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies. Together with C206, C207, C208, R204 and CR203, they build up the reference oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85
°
C. It also provides 16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.
The loop filter consists of C231, C232, C233, R231, R232 and R233. This filter provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur passing through.

To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U201 to put the synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at U201, pin 43.
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V square waves, 180 degrees out of phase, are first shifted to 5V, then along with regulated 5V, put through arrays of diodes and capacitors to build up 13.3V at U201-47.

2.8 Voltage Controlled Oscillator (VCO)
The VCOB IC (U241), shown in Figure 2-8, in conjunction with the Fractional-N synthesizer (U201) generates RF in both the receive and the transmit modes of operation. The TRB line (U241-19) determines which oscillator and buffer are enabled. A sample of the RF signal from the enabled oscillator is routed from U241-12, through a low pass filter, to the prescaler input (U201-32). After frequency comparison in the synthesizer, a resultant DC control voltage is received at the VCO. When the PLL is locked on frequency, this voltage can vary between 3.5 V and 9.5V.
The VCOB IC (U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.

U241-10 is injected into the input of the PA module (U101-16). Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through U201-41.
When a high impedance is applied to U241-19, the VCO operates in battery saver mode. In this mode, both the receive and transmit oscillators, as well as the receive transmit and prescaler buffer, are turned off.
2.9 VHF Transmitter
The VHF transmitter consists of the following basic circuits as shown in Figure 2-9:
•Power amplifier. •Antenna switch/harmonic filter.•Antenna matching network.•Power control integrated circuit (PCIC).
Figure 2-9.
VHF Transmitter Block Diagram
2.9.1 Power Amplifier
The power amplifier consists of two devices:
•LDMOS driver IC (U3501) and •LDMOS PA (Q3501)
The LDMOS driver IC contains a 2-stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pins 6 and 7) with an input signal of 2mW (3dBm) (pin16). The current drain is typically around 130mA while operating in the frequency range of 136-174MHz.
The LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W. The current drain is typically around 1800mA while operating in the frequency range of 136-174MHz. The power output can be varied by changing the bias voltage.
2.9.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (D3521 and D3551), a pi network (C3531, L3551 and C3550), and three
current limiting resistors (R3571, R3572, R3573). In the transmit mode, B+ at PCIC (U3502) pin 23 will go low and turn on Q3561 where a B+ bias is applied to the antenna switch circuit to bias the diodes “on”. The shunt diode (D3551) shorts out the receiver port and the pi network (which operates as a quarter wave transmission line), and transforms the low impedance of

Matching Network/

the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, creating a low attenuation path between the antenna and receiver ports.
2.9.3 Harmonic Filter
The harmonic filter consists of C3532 to C3536, L3531 and L3532. This network forms a low-pass filter to attenuate harmonic energy of the transmitter to specifications level. The harmonic filter insertion loss is typically less than 1.2dB.
2.9.4 Antenna Matching Network
A matching network made up of L3538, C3537 and C3539 is used to match the antenna's impedance to the harmonic filter. This optimizes the performance of the transmitter and receiver into an antenna.
2.9.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the PCIC (U3502) to control the power output of the radio by maintaining the radio current drain. The current to the final stage of the power module is supplied through R3519, which provides a voltage proportional to the current drain. This voltage is then fed back to the Automatic Level Control (ALC) within the PCIC to provide loop stability.
The PCIC also contains internal digital to analog converters (DACs) that provide the reference voltage of the control loop. The voltage level is controlled by the microprocessor through the data line of the PCIC.
The resistors and integrators within the PCIC, and the external capacitors (C3562, C3563 and C3565) control the transmitter rise and fall time and are necessary to reduce the power splatter into adjacent channels.
U3503 and its associated components act as a temperature cut back circuit. This provides the necessary voltage to the PCIC to cut the transmitter power if the radio temperature gets too high.
2-14 VHF Receiver
2.10 VHF Receiver
The VHF receiver consists of front end, back end, and automatic gain control circuits. A block diagram of the VHF receiver is shown in Figure 2-10. Detailed descriptions of these features are contained in the paragraphs that follow.
Figure 2-10.
VHF Receiver Block Diagram
2.10.1 Receiver Front-End
The RF signal is received by the antenna and applied to a low-pass filter consisting of L3531, L3532, C3532 to C3536. The filtered RF signal is passed through the antenna switch. The antenna switch circuit consists of two PIN diodes (D3521 and D3551) and a pi network (C3531, L3551 and C3550).The RF signal is then applied to a varactor tuned bandpass filter which consists of L3301, L3303, C3301 to C3304 and D3301. The filter is tuned by applying a control voltage to the varactor diode (D3301) in the filter.
The bandpass filter is electronically tuned by the DACRx from IC U404 which is controlled by the microprocessor. Depending on the carrier frequency, the DACRx supplies the tuning voltage to the varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter across the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q3302 via C3306. After being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass filter, consisting of L3305, L3306, C3311 to C3314 and D3302.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth of the filter is about 12 MHz. This enables the filters to be electronically controlled by using a single control voltage which is DACRx.

VHF Receiver 2-15
The output of the post-RF amplifier filter is connected to the passive double balanced mixer which consists of T3301, T3302 and CR3301. Matching of the filter to the mixer is provided by C3317, C3318 and L3308. After mixing with the first LO signal from the voltage controlled oscillator (VCO) using high side injection, the RF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transferred to the crystal filter (Y3200) through a resistor pad (R3321 - R3323) and a diplexer (C3320 and L3309). Matching to the input of the crystal filter is provided by C3200 and L3200. The crystal filter provides the necessary selectivity and intermodulation protection.
2.10.2 Receiver Back-End
The output of crystal filter Y3200 is matched to the input of IF amplifier transistor Q3200 by capacitor C3203. Voltage supply to the IF amplifier is taken from the receiver 5 volts (R5). The controlled gain IF amplifer provides a maximum gain of about 10dB. The amplified IF signal is then coupled into U3220 pin 3 via L3202, C3207, and C3230 which provides impedance matching for the IF amplifier and U3220.
The IF signal applied to pin 3 of U3220 is amplified, down-converted, filtered, and then demodulated, to produce the recovered audio at pin 27 of U3220. This IF IC is electronically programmable, and the amount of filtering, which is dependent on the radio channel spacing, is controlled by the microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is replaced by internal filters in the IF module (U3220).
The IF IC uses a type of direct conversion process, whereby the externally generated second LO frequency is divided by two in U3220 so that it is very close to the first IF frequency. The IF IC (U3220) synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC.
In the absence of an IF signal, the VCO “searches” for a frequency, or its frequency will vary close to twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The second LO/VCO is a Colpitts oscillator built around transistor Q3270. The VCO has a varactor diode, D3270, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting of C3278 to C3280, R3274 and R3275.
The IF IC (U3220) also provides a received signal-strength indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor, and is used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U3220 is also used for squelch control. The signal is routed to U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio signal is also routed to U404 for processing before going to the audio amplifier for amplification.
2.10.3 Automatic Gain Control (AGC)
The front end automatic gain control circuit provides automatic reduction of gain of the front end RF amplifier via feedback. This prevents overloading of backend circuits and is achieved by drawing some of the output power from the RF amplifier output. At high radio frequencies, capacitor C3327 provides the low impedance path to ground for this purpose. CR3302 is a PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed to turn the PIN diode on. Transistor Q3301 provides this current.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q3301 to saturation, i.e., turned on. RSSI is produced by U3220 and is proportional to the gain of the RF amplifier and the input power to the radio.
Resistors R3304 and R3305 make up a voltage divider designed to turn on Q3301 at certain RSSI levels. To turn on Q3301 the voltage across R3305 must be greater or equal to the voltage across R3324, plus the base-emitter voltage (Vbe) present at Q3301. Capacitor C3209 is used to dampen any instability while the AGC is turning on. The current flowing into the collector of Q3301, a high
2-16 Synthesizer
current gain NPN transistor, is drawn through the PIN diode to turn it on. Maximum current flowing through the pin is limited by resistors R3316, R3313, R3306 and R3324. Feedback capacitor C3326 is used to provide some stability to this high gain stage.
An additional gain control circuit is formed by Q3201 and associated components. Resistors R3206 and R3207 are voltage dividers designed to turn on Q3201 at a significantly higher RSSI level than the level required to turn on PIN diode control transistor Q3301. In order to turn on Q3201 the voltage across R3207 must be greater or equal to the voltage across R3208 + Vbe. As current starts flowing into the collector of Q3201, it reduces the bias voltage at the base of IF amplifier transistor Q3200 and in turn, the gain of the IF amplifier. The gain is then controlled in a range of -30dB up to +10dB.
2.10.4 Frequency Generation Circuitry
The Frequency Generation Circuitry shown in Figure 2-11is composed of two main ICs, the Fractional-N synthesizer (U3701), and the VCO/Buffer IC (U3801). Designed in conjunction to maximize compatibility, the two ICs provide many of the functions that normally would require additional circuitry. The synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer to the schematic for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which is provided from U3711 and U3201, respectively. The synthesizer, in turn, generates a superfiltered 4.5V which powers U3801.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry. Programming for the synthesizer is accomplished through the data, clock and chip select lines from the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U3701. Internally, the audio is digitized by the Fractional-N and applied to the loop divider to provide low-port modulation. The audio runs through an internal attenuator for modulation balancing purposes before going out to the VCO.

The Fractional-N Synthesizer shown in Figure 2-12 uses a 16.8MHz crystal (Y3761) to provide a reference for the system. The LVFractN IC (U3701) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference frequencies.

During the transmit condition, when PTT is depressed, 3.2 volts is applied to U3801, pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U3801. The RF signal at U3801, pin 10 is injected into the input of the PA module (U3501, pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through U3701, pin 41.

Maintenance
3.1 Introduction
This section of the manual describes:
• preventive maintenance• safe handling of CMOS devices• repair procedures and techniques
3.2 Preventive Maintenance
The radios do not require a scheduled preventive maintenance program; however, periodic visual inspection and cleaning is recommended.
3.2.1 Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches are functional. It is not recommended to inspect the interior electronic circuitry.
3.2.2 Cleaning
The following procedures describe the recommended cleaning agents and the methods to be used when cleaning the external and internal surfaces of the radio. External surfaces include the front cover, housing assembly, and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit boards and their components is isopropyl alcohol (70% by volume).
1. Cleaning External Plastic Surfaces
The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be used to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.
2. Cleaning Internal Circuit Boards and Components
Isopropyl alcohol may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged material out and away from the inside of the radio. Make sure that controls or tunable components are not soaked with alcohol. Do not use high-pressure air to hasten the drying process since this could cause the liquid to collect in unwanted places. Upon completion of the cleaning process, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol to the frame, front cover, or back cover.
NOTE Internal surfaces should be cleaned only when the radio is disassembled for servic-ing or repair.
CAUTION: The effects of certain chemicals and their vapors can have harmful results on cer-tain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided.!
3-2 Safe Handling of CMOS and LDMOS
3.3 Safe Handling of CMOS and LDMOS
Complementary metal-oxide semiconductor (CMOS) and lateral diffusion metal oxide semiconductor (LDMOS) devices are used in this family of radios. CMOS characteristics make them susceptible to damage by electrostatic or high voltage charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent device damage during disassembly, troubleshooting, and repair.
Handling precautions are mandatory for CMOS circuits and are especially important in low humidity conditions. DO NOT attempt to disassemble the radio without first referring to the CMOS CAUTION paragraph in the Disassembly and Reassembly section of the Basic Manual.
3.4 General Repair Procedures and Techniques
1. Parts Replacement and Substitution
When damaged parts are replaced, identical parts should be used. If the identical replacement component is not locally available, check the parts list for the proper Motorola part number and order the component from the nearest Motorola Communications parts center listed in the “Piece Parts” section of this manual (See Chapter 1).
2. Rigid Circuit Boards
This family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not accessible, some special considerations are required when soldering and unsoldering components. The printed-through holes may interconnect multiple layers of the printed circuit. Therefore, care should be exercised to avoid pulling the plated circuit out of the hole.
When soldering near the 20-pin and 40-pin connectors:
• avoid accidentally getting solder in the connector. • be careful not to form solder bridges between the connector pins • closely examine your work for shorts due to solder bridges.
3. Flexible Circuits
The flexible circuits are made from a different material than the rigid boards and different techniques must be used when soldering. Excessive prolonged heat on the flexible circuit can damage the material. Avoid excessive heat and excessive bending.
For parts replacement, use the ST-1087 Temperature-Controlled Solder Station with a 600-700 degree tip, and use small diameter solder such as ST-633. The smaller size solder will melt faster and require less heat to be applied to the circuit.
To replace a component on a flexible circuit:
• grasp the edge of the flexible circuit with seizers (hemostats) near the part to be removed • pull gently• apply the tip of the soldering iron to the component connections while pulling with the seizers.
Do not attempt to puddle out components. Prolonged application of heat may damage the flexible circuit.
Chip Components
Use either the RLN-4062 Hot-Air Repair Station or the Motorola 0180381B45 Repair Station for chip component replacement. When using the 0180381B45 Repair Station, select the TJ-65 mini-thermojet hand piece. On either unit, adjust the temperature control to 700 degrees F. (370 degrees C), and adjust the airflow to a minimum setting. Airflow can vary due to component density.
NOTE Always use a fresh supply of alcohol and a clean container to prevent contamination by dissolved material (from previous usage).
General Repair Procedures and Techniques 3-3
❏
To remove a chip component: • Use a hot-air hand piece and position the nozzle of the hand piece approximately 1/8" (0.3 cm)
above the component to be removed. • Begin applying the hot air. Once the solder reflows, remove the component using a pair of
tweezers. • Using a solder wick and a soldering iron or a power desoldering station, remove the excess
solder from the pads.
❏
To replace a chip component using a soldering iron: • Select the appropriate micro-tipped soldering iron and apply fresh solder to one of the solder
pads. • Using a pair of tweezers, position the new chip component in place while heating the fresh sol-
der. • Once solder wicks onto the new component, remove the heat from the solder. • Heat the remaining pad with the soldering iron and apply solder until it wicks to the component.
If necessary, touch up the first side. All solder joints should be smooth and shiny.
❏
To replace a chip component using hot air:• Use the hot-air hand piece and reflow the solder on the solder pads to smooth it. • Apply a drop of solder paste flux to each pad. • Using a pair of tweezers, position the new component in place. • Position the hot-air hand piece approximately 1/8” (0.3 cm) above the component and begin
applying heat. • Once the solder wicks to the component, remove the heat and inspect the repair. All joints
should be smooth and shiny.
Shields
Removing and replacing shields will be done with the R-1070 station with the temperature control set to approximately 415
°
F (215
°
C) [445
°
F (230
°
C) maximum]
❏
To remove the shield: • Place the circuit board in the R-1070’s holder. • Select the proper heat focus head and attach it to the heater chimney. • Add solder paste flux around the base of the shield. • Position the shield under the heat-focus head. • Lower the vacuum tip and attach it to the shield by turning on the vacuum pump. • Lower the focus head until it is approximately 1/8” (0.3 cm) above the shield. • Turn on the heater and wait until the shield lifts off the circuit board. • Once the shield is off, turn off the heat, grab the part with a pair of tweezers, and turn off the
vacuum pump. • Remove the circuit board from the R-1070’s circuit board holder.
❏
To replace the shield: • Add solder to the shield if necessary, using a micro-tipped soldering iron. • Next, rub the soldering iron tip along the edge of the shield to smooth out any excess solder.
Use solder wick and a soldering iron to remove excess solder from the solder pads on the cir-cuit board.
• Place the circuit board back in the R1070’s circuit board holder. • Place the shield on the circuit board using a pair of tweezers. • Position the heat-focus head over the shield and lower it to approximately 1/8” (0.3 cm) above
the shield. • Turn on the heater and wait for the solder to reflow.• Once complete, turn off the heat, raise the heat-focus head and wait approximately one minute
for the part to cool. • Remove the circuit board and inspect the repair. No cleaning should be necessary.

Power Up Self-Test Error Codes 3-7
3.8 Power Up Self-Test Error Codes
Turning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM hardware and EEPROM checksum. If these checks are successful, the radio generates two high-pitched self-test pass tones. If the self-test is not successful, one low-pitched tone is heard. Radios with displays are able to display the error codes. The displayed error codes and related corrections are as follows:
• “RAM ERR” for <RAM Test Error>• “ROM CS” for <ROM Checksum Error>• “EPM ERR” for <EEPROM Hardware Test Error>• “EPM CS” for <EEPROM Checksum Error>
NOTE Radio without display emits only “bonk” (300 Hz) tone if it fails the self-test.
Table 3-2 Error Codes
Error Code Explanation Corrective Action
“RAM ERR” RAM Test Failure Retest radio by turning it off and turning it on again. If message reoccurs, replace main board or send radio to nearest Motorola Depot.
“ROM CS” ROM Checksum is wrong.

Schematic Diagrams, Overlays, and Parts Lists
4.1 Introduction
This section provides schematic diagrams, overlays, and parts lists for the radio circuit boards and interface connections.
4.1.1 Notes For All Schematics and Circuit Boards
* Component is frequency sensitive. Refer to the Electrical Parts List for value and usage.
1.
Unless otherwise stated, resistances are in Ohms (k = 1000), and capacitances are in picofarads (pF) or microfarads (µF).
2.
DC voltages are measured from point indicated to chassis ground using a Motorola DC multime-ter or equivalent. Transmitter measurements should be made with a 1.2 µH choke in series with the voltage probe to prevent circuit loading.
3.
Reference Designators are assigned in the following manner:
400/500 Series = Controller
600 Series = Keypad Board
3200 Series = IF Circuitry
3300 Series = Receiver
3500 Series = Transmitter
3700 and 3800 Series = Frequency Generation
4.
Interconnect Tie Point Legend:
UNSWB+ = Unswitched Battery Voltage (7.5V)
SWB+ = Switched Battery Voltage (7.5V)
R5 = Receiver Five Volts
CLK = Clock
Vdda = Regulated 3.3 Volts (for analog)
Vddd = Regulated 3.3 Volts (for digital)
CSX = Chip Select Line (not for LVZIF)
SYN = Synthesizer
DACRX = Digital to Analog Voltage (For Receiver Front End Filter)
VSF = Voltage Super Filtered (5 volts)
VR = Voltage Regulator
