CHAPTER 3. Circuit Description
1. RF Transmit/Receive Part 1.1 Overview
The Tx and Rx part employs the Direct-Conversion system. The Tx and Rx frequencies are respectively
824.04~848.97 and 869.04~893.97 for cellular and 1850~1910 and 1930~1990 for PCS. The block diagram is
shown in [Figure 1-1]. RF signals received through the antenna are seperated by the Quintplexer.
RF Signal fed into the low noise amplifier (LNA) through the Quintplexer. Then, they are fed into RFR6000. In
RFR6000, the RF signal is changed into baseband signal directly. Then, this signal is changed into digital signal
by the analog to digital converter (ADC, A/D Converter), and the digital circuit part of the MSM(Mobile Station
Modem) 6100 processes the data from ADC. The digital processing part is a demodulator.
In the case of transmission, RFT6100 receives OQPSK-modulated anlaog signal from the MSM6100.
The RFT6100 connects directly with MSM6100 using an analog baseband interface. In RFT6100, the baseband
quadrature signals are upconverted to the Cellular or PCS frequency bands and amplified to provide signal drive
capability to the power amp.
After that, the RF signal is amplified by the Power Amp in order to have enough power for radiation. Finally,
the RF signal is sent out to the cell site via the antenna after going through the Quintplexer.

1.2 Description of Receive Part Circuit 1.2.1 Quintplexer (U101)
The Quintplexer consists of the Rx bandpass filter (BPF), the Tx BPF and the GPS filter(BPF) which has
the function of separating Tx, Rx and GPS signals in the full Triplex system for using the common antenna. The
Tx part BPF is used to suppress noises and spurious out of the Tx frequency band. The Rx BPF is used to
receive only Rx signal coming from the antenna, which is usually called preselector. It’s main function is to
limit the bandwidth of spectrum reaching the LNA and mixer, attenuate receiver spurious response and suppress
local oscillator energy. As a result frequency sensitivity and selectivity of mobile phone increase. The

1.2.2 LNAs (U107)
The RFL6000 has cellular and PCS LNAs, respectively. The characteristics of Low Noise Amplifier (LNA)
are low noise figure, high gain, high intercept point and high reverse isolation. The frequency selectivity
characteristic of mobile phone is mostly determined by LNA.

1.2.3 Down-converter Mixers and GPS LNA (U111)
The RFR6000 device performs signal down-conversion for Cellular, PCS and GPS tri-band applications. It
contains all the circuitry (with the exception of external filters) needed to support conversion of received RF
signals to baseband signals. The three downconverting Mixers (Cellular, PCS and GPS), and an LO Buffer
Amplifier to buffer the RF VCO to the RF Transmit Upconverter. The GPS LNA & mixers offer the most
advanced and integrated CDMA Rx solution designed to meet cascaded Noise Figure (NF) and Third-order
Intercept Point (IIP3) requirements of IS-98C and J-STD-018 specifications for Sensitivity, Two-Tone
Intermodulation, and Single-tone Desense.
Operation modes and band selection are specially controlled from the Mobile Station Modem MSM6100.

The main function of Rx RF SAW filter is to attenuate mobile phone spurious frequency, attenuate noise
amplified by the LNA and suppress second harmonic originating in the LNA.
1.3 Description of Transmit Part Circuit 1.3.1 RFT6100 (U112)
The RFT6100 baseband-to-RF Transmit Processor performs all Tx signal-processing functions required
between digital baseband and the Power Amplifier Modulator (PAM). The baseband quadrature signals are
upconverted to the Cellular or PCS frequency bands and amplified to provide signal drive capability to the PAM.
The RFT6100 includes an mixers for up-converting analog baseband to RF, a programmable PLL for generating
Tx and Rx LO frequency, cellular and PCS driver amplifiers and Tx power control through an 85 dB VGA. As
added benefit, the single sideband upconversion eliminates the need for a band pass filter normally required
between the upconverter and driver amplifier.
I, I/, Q and Q/ signals proceed from the MSM6100 to RFT6100 are analog signal. In CDMA mode, These
signals are modulated by Offset Quadrature Phase Shift King (OQPSK). I and Q are 90 deg. out of phase, and I
and I/ are 180 deg. The mixers in RFT6100 converts baseband signals into RF signals. After passing through
the upconverters, RF signal is inputted into the Power AMP.

AlGaAs/GaAs HBT (heterojunction bipolar transistor) process. The module of power amplifier is made up of an
output end interface circuit including this MMIC. The maximum power that can be inputted through the input
terminal is +17dBm and conversion gain is about 28dB. RF transmit signals that have been amplified through
the power amplifier are sent to the Quintplexer.
1.4 Description of Frequency Synthesizer Circuit 1.4.1 Voltage Control Temperature Compensation Crystal Oscillator (VCTCXO, X100)
The temperature variation of mobile phone can be compensated by VCTCXO. The reference frequency of a
mobile phone is 19.2 MHz. The receiver frequency tuning signals called TRK_LO_ADJ from MSM as 0.5
V~2.5 V DC via R and C filter in order to generate the reference frequency of 19.2 MHz and input it into the
frequency synthesizer. Frequency stability depending on temperature is ±1.5 ppm.
1.4.2 Voltage Controlled Oscillator (VCO, U110)
The external VCO signal is processed by the LO generation and distribution circuits in RFR6000 to create the
PCS and Cellular quadrature downconverter’s LO signals. Likewise, the internal VCO signal of RFR6000 is
processed to create the GPS quadrature downconverter’s LO signal. In all cases, the LO signals applied at the
mixer ports are at the frequency different than the VCO frequency. This assures that the VCO frequency is
different than the RF frequency, an important consideration for Zero-IF processing. The VCO frequency used
are 1715.56~1768.89 MHz for PCS and 1738.08~1787.94 MHz for cellular.

the keypad, LCD part that displays the operation status onto the screen, and a receptacle that receives and sends
out voice and data with external sources.
2.2.2 Voice Processing Part
The voice processing part is made up of an audio codec used to convert MIC signals into digital voice signals
and digital voice signals into analog voice signals, amplifying part for amplifying the voice signals and sending
them to the ear piece, amplifying part that amplifies ringer signals coming out from MSM6100, and amplifying
part that amplifies signals coming out from MIC and transferring them to the audio processor.
2.2.3 MSM (Mobile Station Modem) 6100 Part
MSM is the core elements of CDMA terminal and carries out the functions of CPU, encoder, interleaver,
deinterleaver, Viterbi decoder, Mod/Demod, and vocoder. 2.2.4 Memory Part
The memory part is made up of a NAND Flash memory, SDRAM for storing data.
2.2.5 Power Supply Part
The power supply part is made up of circuits for generating various types of power, used for the digital/voice
processing part.
2.3 Circuit Description 2.3.1 Keypad/LCD and Receptacle Part
Once the keypad is pressed, the key signals are sent out to MSM6100 for processing. In addition, when the
key is pressed, the keypad/LCD lights up through the use of 20 LEDs. The terminal status and operation are
displayed on the screen for the user with the characters and icons on the LCD. Moreover, it exchanges audio signals and data with external sources through the receptacle, and then receives
power from the battery or external batteries.
2.3.2 Audio Processing Part
Copyright@2007 LG Electronics. Inc. All right reserved.
LGE Internal Use Only
Only for training and serving purposes - 25 -
MIC signals are amplified through OP AMP, inputted into the audio codec(included in MSM6100) and
converted into digital signals. Oppositely, digital audio signals are converted into analog signals after going
through the audio codec. These signals are amplified at the audio amplifier and transmitted to the ear-piece. The
signals from MSM6100 activate the ringer by using signals generated in the timer in MSM6100.
2.3.3 MSM Part
MSM6100 is the core element of CDMA system terminal that includes ARM9TDMI microprocessor core. It
supports both CDMA and Digital FM, operating in both the cellular and PCS spectrums. The subsystems within
the MSM6100 include a CDMA processor, a DFM processor, a multi-standard Vocoder, an integrated CODEC
with earpiece and microphone amplifiers, general-purpose ADC for subsytem monitoring, an ARM9TDMI
microprocessor, and both Universal Serial Bus(USB) and an RS-232 serial interfaces supporting forward and
reverse link data communications of 307.2 Kbps simultaneously. And it also contains complete digital
modulation and demodulation systems for both CDMA and AMPS cellular standards, as specified in
IS-95-A/B/C.
In MSM, coded symbols are interleaved in order to cope with multi-path fading. Each data channel is
scrambled by the long code PN sequence of the user in order to ensure the confidentiality of calls. Moreover,
binary quadrature codes are used based on walsh functions in order to discern each channel. Data created thus
are 4-phase modulated by one pair of Pilot PN code and they are used to create I and Q data.
When received, I and Q data are demodulated into symbols by the demodulator, and then de-interleaved in
reverse to the case of transmission. Then, the errors of data received from viterbi decoder are detected and
corrected. They are voice-decoded at the vocoder in order to output digital voice data.

IMPORTANTRead This Information Before Using Your Hand-Held Portable Cellular TelephoneFirst introduction in 1984, the hand-held portable Cellular telephone is one of the most exciting and innovative electronic products ever developed.With it you can stay in contact with your office, your home, emergency service, and others. For the safe and efficient operation of your phone, observe these guidelines.Your Cellular phone is a radio transmitter and receiver. When it is ON, it receives and also sends out radio frequency (RF) energy. The phone operates in the frequency range of 824 MHz to 894 MHz and employs commonly used frequency modulation (FM) techniques. When you use your phone, the Cellular system handling your calls controls the power level at which your phone transmits. The power level can range from 0.006 of a watt to .6 of a watt.
Exposure to Radio Frequency EnergyIn 1991 the Institute of Electrical and Electronics Engineers (IEEE), and in 1992 the American National Standards Institute (ANSI) updates the 1982 ANSI Standard for safety levels with respect to human exposure to RF energy. Over 120 scientists, engineers, and physicians from universities, government health agencies, and industry, after reviewing the available boy of research, developed this updated Standard. In March, 1993, the US Federal Communications Commission (FCC) proposed the adoption of this updated Standard.The design of your phone complies with this updated Standard. Of course, if you want to limit RF exposure even further than the updated ANSI Standard, you may choose to control the duration of your calls and operation your phone in the most power efficient manner.
Efficient Phone OperationFor your phone to operate at the lowest power level, consistent with satisfactory call quality, please observe the following guidelines:If your phone has an extendable antenna, extend it fully. Some models allow you to place a call with the antenna retracted. However, your phone operates more efficiently with the antenna fully extended.Hold the phone as you would any other telephone. While speaking directly into the mouthpiece, position the antenna up and over your shoulder.Do not hold the antenna when the phone is “IN USE”. Holding the antenna affects call quality and may cause the phone to operated at a higher power level than needed.
Antenna Care and ReplacementDo not use the phone with a damaged antenna. If a damaged antenna comes into contact with skin, a minor bum may result. Replace a damaged antenna immediately. Consult your manual to see if you may change your antenna yourself. If so, use only a manufacture approves antenna. Otherwise, take your phone to a qualifies service center for repair.Use only the supplied or approved antenna. Non-approved antennas, modifications, or attachments, could impair call quality, damage the phone, and violate FCC regulations.

DrivingCheck the laws and regulations on the use of Cellular telephones in the areas where you drive. Always obey them. Also, when using your phone while driving, please:Give full attention to the driving. Use hands-free operation, if available, and pull off the road and park before making or answering a call if driving conditions require.
Electronic DevicesMost modem electronic equipment is shielded from RF energy. However, RF energy from Cellular telephones may affect inadequately shielded electronic equipment.RF energy may effect improperly installed or inadequately shielded electronic operating and entertainment system in motor vehicles. Check with the manufacturer or its representative to determine if these systems are adequately shielded from external RF energy. You should check with the manufacturer of any equipment that has been added to your vehicle.Consult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc.) to determine if they are adequately shielded from external RF energy.Turn your phone OFF in health care facilities. When any regulations posted in the areas instruct you to do so. Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy.
AircraftTurn your phone OFF before boarding any aircraft.Use it on the ground only with crew permission. Do not use it in the air.To prevent possible interference with aircraft systems, US Federal Aviation Administration (FAA) regulations require you to have permission from a crew member to use your phone while the plane is on the ground. Using your phone while the plane is in the air.
ChildrenDo not allow children to play with your phone. It is not a toy. Children could hurt themselves or others (by poking themselves or others in the eye with the antenna, for example). Children also could damage the phone, or make calls that increase your telephone bills.
Blasting AreasTo avoid interfering with blasting operations, turn you unit OFF when in a “blasting area” or in areas posted “Turn off two-way radio”. Construction crews often use remote control RF devices to set off explosives.
Potentially Explosive AtmospheresTurn your phone OFF when in any area with a potentially explosive atmosphere. It is rare, but your phone or accessories could generate sparks. Sparks in such area could cause an explosion or fire resulting in bodily injury or even death.Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fueling areas such as gas station; below deck on boats; fuel or chemical transfer or storage facilities; areas where the air contains chemical 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.

Soft Handoff. A handoff occurring while the mobile station is in the Mobile Station Control on the Traffic Channel
State. This handoff is characterized by commencing communications with a new base station on the same CDMA
frequency assignment before terminating communications with the old base station. See also Hard Handoff.
SOM. Start-of-Message Bit.
SPS. Symbols per second.
- An identification of certain characteristics of a mobile station. Classes are defined in Table 2.3.3-1.
Status Information. The following status information is used to describe mobile station operation when using the
analog system.
Serving-System Status. Indicates whether a mobile station is turned to channels associated with System A or
System B.
First Registration ID Status. A status variable used by the mobile station in association with its processing of
received Registration ID messages.
First Location Area ID Status. A status variable used by the mobile station in association with its processing of
received Location Area ID messages.
Location Registration ID Status. A status variable used by the mobile station in association with its processing of
power-up registration and location-based registration.
First Idle ID Status. A status variable used by the mobile station in association with its processing of the Idle Task.
Local Control Status. Indicates whether a mobile station must respond to local control messages.
Roam Status. Indicates whether a mobile station is in its home system.
Termination Status. Indicates whether a mobile station must terminate the call when it is on an analog voice
channel.
Supervisory Audio Tone (SAT). One of three tones in the 6 kHz region that is transmitted on the forward analog
voice channel by a base station and transponder on the reverse analog voice channel by as mobile station.
Supplementary Digital Color Code (SDCC1, SDCC2). Additional bits assigned to increase the number of color
codes from four to sixty four, transmitted on the forward analog control channel.
Symbol. See Code Symbol and Modulation Symbol.
Sync Channel. Code channel 32 in the Forward CDMA Channel which transports the synchronization message to the
mobile station.
Sync Channel Superframe. An 80ms interval consisting of three Sync Channel frames (each 26.666…ms in length).
System. A system is a Cellular telephone service that covers a geographic area such as a city. Metropolitan region,
country, or group of countries. See also Network.
System Time. The time reference used by the system. System Time is synchronous to UTC time (except for leap
seconds) and used the same time origin as GPS time. Offset by the propagation delay from the base station to the
mobile station. See also Universal coordinated Time.
Timer-Based Registration. A registration method in which the mobile station registers whenever a counter reaches
a predetermined value. The counter is incremented an average of once per 80 ms period.
Time Reference. A reference established by the mobile station that is synchronous with the earliest arriving
multipath component used for demodulation.

TOLR. See Transmit Objective Loudness Rating.
Traffic Channel. A communication path between a mobile station and base station used for user and signaling
traffic. The term Traffic Channel implies a Forward Traffic Channel and Reverse Traffic Channel pair. See also
Forward Traffic Channel and Reverse Traffic Channel.
Traffic Channel Preamble. A sequence of all-zero frames that is sent at the 9600 bps rate by the mobile station on
the Reverse Traffic Channel. The Traffic Channel preamble is sent during initialization of the Traffic Channel.
Transmit Objective Loudness Rating (TOLR). A perceptually weighted transducer gain of telephone transmitters
relation sound pressure at the microphone to voltage at a reference electrical termination. It is normally specified in
dB relative to one millivolt per Pascal. See IEEE Standard 269-1992, IEEE Standard 661-1979, CCITT
Recommendation P.76 , and CCITT Recommendation. P.79
Unique Challenge-Response Procedure. An exchange of information between a mobile station and a base station
for the purpose of confirming the mobile station’s identity. The procedure is initiated by the base station and is
characterized by the use of a challenge-specific random number (i.e., RANDU) instead of the random variable
broadcast globally (RAND).
Unique Random Variable (RANDU). A 24-bit random number generated by the base station in support of the
Unique Challenge-Response procedure.
Universal Coordinated Time (UTC). An internationally agreed-upon time scale maintained by the Bureau
International de l’Heure (BIH) used as the time reference by nearly all commonly available time and frequency
distribution systems i.e., WWW, WWVH, LORAN-C, Transit, Omega, and GPS.
UTC. Universal Temps Coordine. See Universal Coordinated Time.
Voice Channel. See Analog Voice Channel.
Voice Mobile Attenuation Code (VMAC). A 3-bit field in the Extended Address Word commanding the initial
mobile power level when assigning a mobile station to an analog voice channel.
Voice Privacy. The process by which user voice transmitted over a CDMA Traffic Channel is a afforded a modest
degree of protection against eavesdropping over the air.
Walsh Chip. The shortest identifiable component of a Walsh function. There are 2N Walsh chips in one Walsh
function where N is the order of the Walsh function. On the Forward CDMA channel one Walsh chip equals
1/1.2288MHz, or 813.802…ns. On the Reverse CDMA Channel, one Walsh chip equals 4/1.2288MHz, or 3.255….
Walsh Function. One of 2N time orthogonal binary functions (note that the functions are orthogonal after mapping
‘0’ to 1 and ‘1’ to –1).
Zone-Based Registration. An autonomous registration method in which the mobile station registers whenever it
