www.DataSheet4U.com DATA SHEET SKY77182 Power Amplifier Module for WCDMA / HSDPA (1920–1980 MHz) Applications WCDMA Handsets HSDPA Handsets Personal Communications Services (PCS) Wireless local loop (WLL) Description The SKY77182 Power Amplifier module is a fully matched 8-pad surface mount module developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient power amplifier packs full coverage of the 1920–1980 MHz bandwidth into a single compact package. The SKY77182 meets the stringent spectral linearity requirements of HSDPA (High Speed Downlink Packet Access) data transmission with high power added efficiency for power output of up to 28 dBm. Because of high efficiencies attained throughout the entire power range, the SKY77182 delivers unsurpassed talk-time advantages. The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The MMIC includes on-board bias circuitry, as well as input and interstage matching circuits. The output match is realized off-chip within the module package to optimize efficiency and power performance into a 50 Ω load. This device is manufactured with Skyworks’ InGaP GaAs Heterojunction Bipolar Transistor (HBT) process that provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. Primary bias to the SKY77182 is supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other...
