The SKY77602 Power Amplifier Module (PAM) is a fully matched, 22-pad, surface mount module developed for Wideband Code Division Multiple Access (WCDMA) and CDMA2000 applications. This small and efficient module packs full coverage for WCDMA Bands I, II, IV, V, and VIII, and for CDMA2000 Bands I, II, IV, and V into a single compact package. The SKY77602 meets the stringent spectral linearity requirements of WCDMA/CDMA2000 transmission, with high power added efficiency for power output to 28 dBm for Bands I, IV, V, 28.5 dBm for Band II, and 28.3 dBm for Band VIII. The SKY77602 meets the stringent spectral linearity requirements of High Speed Downlink Packet Access (HSDPA) data transmission with high power added efficiency. An integrated directional coupler eliminates the need for any external coupler.

The SKY77602 PAM 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. No regulated voltage is required. Power down is accomplished by setting the voltage on VEN_H or VEN_L to zero volts. No external supply side switch is needed as typical "off" leakage is a few microamperes with full primary voltage supplied from the battery.
