描述 Description

The SKY77712 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’ SKY77712 also supports TD-SCDMA multi-slot operation.

This 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.

A 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.

This 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.

Power-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.
