DATA SHEET SKY65131: WLAN Power Amplifier Module Applications Description • IEEE802.11 b/g WLAN The Skyworks SKY65131 is a Microwave Monolithic Integrated Circuit (MMIC) Power Amplifier (PA) with superior output power, linearity, and efficiency. These features make the SKY65131 ideal for Wireless Local Area Network (WLAN) applications. • ISM band transmitters • WCS fixed wireless • Wireless access nodes Features • Single 3.3 V supply • Linear output power of +28 dBm for IEEE802.11b mask • Linear output power of +26 dBm for IEEE802.11g mask • High PAE of 38 percent The device is fabricated using Skyworks high reliability Indium Gallium Phosphide (InGaP) Heterojunction Bipolar Transistor (HBT) technology. The device is internally matched and mounted in a 4 x 4 mm, Multi-Chip Module (MCM) Surface-Mounted Technology (SMT) package, which allows for a highly manufacturable low cost solution. The device package and pinout are shown in Figure 1. A block diagram of the SKY65131 is shown in Figure 2. • Output power detector: 20 dB dynamic range V_DET • Small MCM (16-pin, 4 x 4 mm), Pb-free SMT package (MSL3, 250 °C per JEDEC J-STD-020) VCC_DET • Internal RF match and bias circuits GND • Superior gain flatness 16 15 14 13 VDET_CNTL 2 12 RF_OUT RF_IN 3 11 RF_OUT VCC1 4 10 GND VC_BIAS 5 9 VCC2 GND 1 RF_IN 6 7 8 VREF2 PA_ON Skyworks offers lead (Pb)-free “environmentally friendly” packaging that is RoHS compliant (European Parliament for the Restriction of Hazardous Substances).

SKY65131 Block Diagram Technical Description The SKY65131 PA contains all of the needed RF matching and DC biasing circuits. The device also provides an output power detector voltage and the ability to switch the PA on or off with a simple control signal. The SKY65131 is a two-stage, HBT InGaP device optimized for high linearity and power efficiency. These features make the device suitable for wideband digital applications, where PA linearity and power consumption are of critical importance (e.g., WLANs). The device has been characterized with the highest specified data rates for 802.11b (11 Mbps) and 802.11g (54 Mbps). Under these stringent test conditions, the device exhibits excellent spectral purity and power efficiency. 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 SKY65131 is rated to Moisture Sensitivity Level 3 (MSL3) at 250 °C. It can be used for lead or lead-free soldering. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. precaution should be taken to ensure that the part is not subjected to temperatures exceeding 250 °C for more than 10 seconds. For details on both attachment techniques, precautions, and handling procedures recommended by Skyworks, please refer to Skyworks Application Note, PCB Design and SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752. Additional information on standard SMT reflow profiles can also be found in the JEDEC Standard J-STD-020. 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. Electrical and Mechanical Specifications Signal pin assignments and functional pin descriptions are described in Table 1. The absolute maximum ratings of the SKY65131 are provided in Table 2. Electrical specifications are provided in Table 3. Typical performance characteristics are shown in Figures 3 through 9. A schematic diagram of the SKY65131 Evaluation Board is shown in Figure 10. A PCB layout footprint for the SKY65131 is provided in Figure 14. Package dimensions for the SKY65131 16-pin MCM are shown in Figure 15, and tape and reel dimensions are shown in Figure 16. If the part is attached in a reflow oven, the temperature ramp rate should not exceed 5 °C per second. Maximum temperature should not exceed 250 °C.
