The SKY77198-12 Power Amplifier Module (PAM) is a fully matched, 10-pad, surface mount moduledeveloped for Time Division Synchronous Code Division Multiple Access (TD-SCDMA) applications.Skyworks’ SKY77198-12 also supports TD-SCDMA multi-slot operation.\n\nThis small and efficient module packs full 1880–1920 MHz and 2010-2025 MHz bandwidth coverageinto a single compact package. The PAM meets the stringent spectral linearity requirements ofTD-SCDMA transmission, with high power added efficiency for power output of up to 28 dBm.\n\nA single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all activecircuitry in the module such as on-board bias circuit and input and interstage matching circuits.Output match is realized off-chip within the module package to optimize efficiency and powerperformance into a 50 Ω load.\n\nThis device is manufactured with Skyworks’ InGaP GaAs Heterojunction Bipolar Transistor (HBT) BiFETprocess that provides for all positive voltage DC supply operation while maintaining high efficiencyand good linearity.\n\nPower-down is accomplished by setting the voltage on VENABLE to zero volts. No external supply sideswitch is needed as typical “off” leakage is a few microamperes with full primary voltage suppliedfrom the battery.
