Applications
* PCS/DCS/UMTS * Repeaters * WLL and ISM bands * Mobile radio * Telematics
Description
Skyworks SKY65105 Power Amplifier (PA) is a fully matched, 12-pin Multi-Chip Module (MCM) surface mount module, developed for Personal Communications System (PCS), Digital Communications System (DCS), and Universal Mobile Telephone System (UMTS) applications. Wireless Local Loop (WLL) and Industrial, Scientific, Medical (ISM) applications are also supported. This small, power-efficient PA has a full 1700 to 2200 MHz bandwidth coverage packed into a single compact package. All active circuitry in the module is contained in a single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC). The SKY65105 is manufactured with Skyworks Aluminum (Al) GaAs Heterojunction Bipolar Transistor (HBT) process, which allows for single supply operation while maintaining high efficiency and good linearity. Figure 1 shows a functional block diagram for the SKY65105. The SKY65105 is packaged in a small, 12-pin 8 x 8 mm Multi-Chip Module (MCM) package. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

Evaluation Board Description
Skyworks SKY65105 Evaluation Board is used to test the performance of the SKY65105 PA. The Evaluation Board schematic diagram is shown in Figure 11. The schematic shows the basic design of the board for the 1700 to 2200 MHz range. An assembly drawing for the Evaluation Board is shown in Figure 12 and the layer detail is provided in Figure 13. Circuit Design Considerations The following design considerations are general in nature and must be followed regardless of final use or configuration 1. Paths to ground should be made as short as possible. 2. The ground pad of the SKY65105 PA has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the amplifier. As such, design the connection to the ground pad to dissipate the maximum wattage produced to the circuit board. Multiple vias to the grounding layer are required. 3. Two external output bypass capacitors (0.01 F and 4.7 F) are required on the VCC1 (pin 12) supply input. The same two capacitors are also required on the VCC2 (pin 4) supply input. Both capacitors should be placed in parallel between the supply line and ground. Also, a bypass capacitor of 0.01 F is required on the VREF input (pin 3). See Figure 11 for a detailed diagram. 4. VCC1 (pin 12) and VCC2 (pin 4) may be connected together at the supply.
5. At the RF input (pin 2), a DC blocking capacitor is required. 6. The RF output includes an onboard internal DC blocking capacitor. All impedance matching is provided internally. Therefore, the application only needs to provide a good 50 load. Testing Procedure Use the following procedure to set up the SKY65105 Evaluation Board for testing. Refer to Figure 14 for guidance: 1. Connect a +5.0 V supply voltage to VCC1 and VCC2, and +3.6 V supply voltage to VREF. If available, enable the current limiting function of the power supplies to 1.0 A for the +5.0 V supply current and 30 mA for the +3.6 V supply current. 2. Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of 7 dBm or less to the Evaluation Board but do NOT enable the RF signal. 3. Connect a spectrum analyzer to the RF signal output port. 4. Enable the power supply. 5. Enable the RF signal. 6. Take measurements. CAUTION: If the input signal exceeds the rated power, the SKY65105 Evaluation Board can be permanently damaged.

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. For packaging details, refer to the Skyworks Application Note, Tape and Reel, document number 101568.
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 SKY65105 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 C. It can be used for lead or lead-free soldering. For additional information, refer to Skyworks Application Note, PCB
Electrostatic Discharge (ESD) Sensitivity
The SKY65105 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.
