DATA SHEET SKY65132: WLAN Power Amplifier Module Applications • IEEE802.11 b/g WLAN • ISM band • WCS fixed wireless • Wireless access nodes Description Skyworks SKY65132 is a Microwave Monolithic Integrated Circuit (MMIC) Power Amplifier (PA) with superior output power, linearity, and efficiency. These features make the SKY65132 ideal for Wireless Local Area Network (WLAN) applications. 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 20-pin, 6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted Technology (SMT) package, which allows for a highly manufacturable low cost solution. The device package and pinout for the 20-pin MCM are shown in Figure 1. A block diagram of the SKY65132 is shown in Figure 2. Features • Single 3.3 V supply • Linear output power of +29 dBm for IEEE802.11b mask • Linear output power of +27 dBm for IEEE802.11g mask • High gain of 33 dB • Output power detector: 20 dB dynamic range • Superior gain flatness • Internal RF match and bias circuits • Small footprint, MCM (20-pin, 6 x 6 mm) Pb-free (MSL3, 250 °C per JEDEC J-STD-020) SMT package Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances) compliant packaging.

SKY65132 Block Diagram Technical Description The SKY65132 PA contains all of the needed RF matching and DC biasing circuits. The device also provides an output power detector voltage. The SKY65132 is a three-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. 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. Electrical and Mechanical Specifications Signal pin assignments and functional pin descriptions are described in Table 1. The absolute maximum ratings of the SKY65132 are provided in Table 2. Electrical specifications are provided in Table 3. Typical performance characteristics are shown in Figures 3 through 10. Figure 11 provides a typical evaluation board schematic. The evaluation board assembly drawing is provided in Figure 12. The evaluation board layer detail is shown in Figure 13 and the layer detail physical characteristics in Figure 14. Package dimensions for the SKY65132 20-pin MCM are shown in Figure 15, and tape and reel dimensions are shown in Figure 16. 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 SKY65132 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. Electrostatic Discharge (ESD) Sensitivity The SKY65132 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.
