Description The SKY66288-11 is a high-efficiency fully input/output matched power amplifier (PA) with high gain and linearity. The compact 5 5 mm PA is designed for the unlicensed spectrum, LTE-advanced small cell base stations operating from 5150 to 5925 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation.
The SKY66288-11 is part of the high-efficiency, pin-to-pin compatible PA family supporting all 3GPP bands.
A block diagram of the SKY66288-11 is shown in Figure 1. The device package and pinout for the 16-pin device are shown in Figure 2. Table 1 lists the pin-to-pin compatible parts in the PA family. Signal pin assignments and functional pin descriptions are described in Table 2.

Technical Description The matching circuits are contained within the device. An on-chip active bias circuit is included within the device for both input and output stages, which provides excellent gain tracking over temperature and voltage variations.
The SKY66288-11 is internally matched for maximum output power and efficiency. The input and output stages are independently supplied using the VCC1, VCC2, and VCC3 supply lines (pins 16, 14, and 12, respectively). The DC control voltage that sets the bias is supplied by the VCBIAS signal (pin 5).
Electrical and Mechanical Specifications The absolute maximum ratings of the SKY66288-11 are provided in Table 3. Recommended operating conditions are specified in Table 4, and electrical specifications are provided in Table 5 (5200 MHz) and Table 6 (5850 MHz).
Typical performance characteristics are shown in Figures 3 through 26.

at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times.

Evaluation Board Description The SKY66288-11 Evaluation Board is used to test the performance of the SKY66288-11 PA. An Evaluation Board schematic is provided in Figure 27. Table 7 provides the Bill of Materials (BOM) list for Evaluation Board components.
An assembly drawing for the Evaluation Board is shown in Figure 28. Board layer details are shown in Figure 29. Layer detail physical characteristics are noted in Figure 30.
Circuit Design Considerations
The following design considerations are general in nature and must be followed regardless of final use or configuration:
Paths to ground should be made as short as possible.
The ground pad of the SKY66288-11 has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Because the circuit board acts as the heat sink, it must shunt as much heat as possible from the device.
Therefore, design the connection to the ground pad to dissipate the maximum wattage produced by the circuit board. Multiple vias to the grounding layer are required.
NOTE: A poor connection between the ground pad and ground increases junction temperature (TJ), which reduces the life of the device.
Evaluation Board Test Procedure
Turn-On Sequence
1. Connect 50 Test Equipment or Load to the input and output RF ports of the Evaluation Board.
2. Connect the DC ground.
3. Connect all VCCs and VBIAS lines to a +5 V supply. Connect PAEN to a 2.0 V supply.
4. Without applying RF, turn on the 5 V supply, then turn on the 2 V PAEN.
5. Apply RF signal data at –30 dBm and observe that the gain of the device is approximately 34.5 dB. Begin measurements.
Turn-Off Sequence
1. Turn off the RF input to the device.
2. Turn off PAEN (set to 0 V).
3. Turn off all VCCs and VBIAS.
NOTE: It is important to adjust the VCC voltage sources so that +5 V is measured at the board. High collector currents drop the collector voltage significantly if long leads are used. Adjust the bias voltage to compensate.

Application Circuit Notes Center Ground. It is extremely important to sufficiently ground the bottom ground pad of the device for both thermal and stability reasons. Multiple small vias are acceptable and work well under the device if solder migration is an issue.
GND (pins 1, 3, 4, 7, 8, 10, 11, 13, and 15). Attach all ground pins to the RF ground plane with the largest diameter and lowest inductance via that the layout allows. Multiple small vias are acceptable and will work well under the device if solder migration is an issue.
VCBIAS (pin 5). The bias supply voltage for each stage, nominally set to +5 V.
RFOUT (pin 9). Amplifier RF output pin (ZO = 50 ). The module includes an onboard internal DC blocking capacitor. All impedance matching is provided internal to the module.
VCC1, VCC2, and VCC3 (pins 16, 15, and 12, respectively). Supply voltage for each stage collector bias is nominally set to 5 V. The evaluation board has inductors L1 and L2. These are place holders, and should be populated with 0 resistors. Bypass and decoupling capacitors C6 through C12 should be placed in the approximate location shown on the evaluation board assembly drawing, although exact placement is not critical.
RFIN (pin 2). Amplifier RF input pin (ZO = 50 ). The module includes an internal DC blocking capacitor. All impedance matching is provided internal to the module.
Package Dimensions The PCB layout footprint for the SKY66288-11 is shown in Figure 31. The typical part marking is shown in Figure 32. Package dimensions are shown in Figure 33, and tape and reel dimensions are provided in Figure 34.
Package and Handling Information Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly.
The SKY66288-11 is rated to Moisture Sensitivity Level 3 (MSL3) at 250 C. It can be used for lead or lead-free soldering. For additional information, refer to Skyworks Application Note, PCB Design and SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752.
Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Production quantities of this product are shipped in a standard tape and reel format.
