www.DataSheet4U.com DATA SHEET SKY77154 System Smart® PA Module for CDMA / AMPS (824–849 MHz) Applications Digital cellular (CDMA) Analog cellular (AMPS) Wireless local loop (WLL) Description The SKY77154 System Smart® Power Amplifier Module (PAM) is a fully matched, 8-pin surface mount module developed for Code Division Multiple Access (CDMA) / Advanced Mobile Phone Service (AMPS) and Wireless Local Loop (WLL) applications. This small and efficient module packs a full 824– 849 MHz bandwidth coverage into a single compact package. The device meets the stringent IS95 CDMA linearity requirements to and exceeding 28 dBm output power, and can be driven to levels beyond 31 dBm for high efficiency in FM mode operation. A low current pin (VCONT) provides improved efficiency for the low RF power range of operation. The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The MMIC contains on-board bias circuitry, as well as input and interstage matching circuits. The output match is realized off-chip and within the module package to optimize efficiency and power performance into a 50-ohm load. This device is manufactured with Skyworks’ 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 SKY77154 is supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other sui...
