SKY65119: 700 - 800 MHz Linear Power Amplifier
Applications
* AMPS/CDMA/TDMA/GSM * Repeaters * WLL and ISM bands * Mobile radio * Paging * Telematics
Description
Skyworks SKY65119 Power Amplifier (PA) is a fully matched, 12-pin lead-free Multi-Chip Module (MCM) developed for cellular, Wireless Local Loop (WLL), and Industrial, Scientific, Medical (ISM) applications. This small, power-efficient PA has a full 700 to 800 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 SKY65119 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 SKY65119. The device package and pinout are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

Technical Description
The SKY65119 is comprised of two amplifier stages. The matching circuits for the input stage, inter-stage, and output stage are contained within the device. The bias circuits for both input and output stages are included within the device for optimum temperature tracking performance. The SKY65119 is internally matched for optimum linearity and efficiency. The input and output stages are independently supplied using the VCC1 and VCC2 supply lines, pins 4 and 12, respectively.
The SKY65119 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. 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.

Evaluation Board Description
Skyworks SKY65119 Evaluation Board is used to test the performance of the SKY65119 PA. The Evaluation Board schematic diagram is shown in Figure 9. The schematic shows the basic design of the board for the 700 to 800 MHz range. An assembly drawing for the Evaluation Board is shown in Figure 10 and the layer detail is provided in Figure 11. 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 SKY65119 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 4) supply input and also on the VCC2 (pin 12) supply input. All four capacitors should be placed in parallel between the supply line and ground. See Figure 9 for a detailed diagram. 4. VCC2 (pin 12) and VCC1 (pin 4) may be connected together at the supply.
5. 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 SKY65119 Evaluation Board for testing. Refer to Figure 12 for guidance: 1. Connect a +5.0 V supply voltage to VCC1 and VCC2. If available, enable the current limiting function of the power supply to 1.0 A. 2. Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of 4 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 SKY65119 Evaluation Board can be permanently damaged.
