www.DataSheet4U.com PRELIMINARY DATA SHEET SKY65137: Power Amplifier for 802.11a WLAN Applications Applications IEEE802.11a WLAN enabled: − access points − media gateways − set top boxes − LCD TVs Other broadband triple-play multimedia applications Description Skyworks SKY65137 is a Microwave Monolithic Integrated Circuit (MMIC) Power Amplifier (PA) with superior output power, linearity, and efficiency. These features make the SKY65137 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 SKY65137 is shown in Figure 2. Features Linear output power of +24 dBm for IEEE802.11a 64-QAM EVM <2.5% High gain of 26 dB Output power detector: 20 dB dynamic range Power shutdown mode RF_IN 18 GND GND Superior gain flatness Internal RF match and bias circuits Small footprint, MCM (20-pin, 6 x 6 mm) Pb-free (MSL3, 260 °C per JEDEC J-STD-020) SMT package Skyworks offers lead (Pb)-free RoHS (Restriction of Hazardous Substances) compliant packaging.
