Dual-Band PA Module for WCDMA/HSDPA Band I and Band VIII

Tue, 04/13/2010 - 7:41am
Skyworks’ SKY77195 Power Amplifier Module (PAM) is a fully matched, 14-pad, surface mount module developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient module packs full WCDMA Band I and Band VIII coverage into a single compact package. The SKY77195 meets the stringent spectral linearity requirements of WCDMA transmission, with high power added efficiency for power output to 27.5 dBm (Band I) and 28 dBm (Band VIII). The SKY77195 meets the stringent spectral linearity requirements of High Speed Downlink Packet Access (HSDPA) data transmission with high power added efficiency. A directional coupler is integrated into the module thus eliminating the need for any external coupler. The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The device is manufactured with Skyworks' InGaP GaAs Heterojunction Bipolar Transistor (HBT) BiFET process that provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity.
