SKY77761-11

DATA SHEET SKY77761-11 Power Amplifier Module for CDMA/ WCDMA/ HSDPA/ HSUPA/ HSPA+ Band I (1920–1980 MHz) Applications WCDMA handsets HSDPA HSUPA HSPA+ CDMA2000 EVDO Features Low voltage positive bias supply 3.0 V to 4.5 V Good linearity High efficiency - 48% at 28.25 dBm Large dynamic range Small, low profile package - 3 mm x 3 mm x 0.9 mm - 10-pad configuration Power down control InGaP Supports low collector voltage operation Digital Enable No VREF required CMOS compatible control signals Integrated Directional Coupler Description The SKY77761-11 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient module packs full 1920–1980 MHz bandwidth coverage into a single compact package. Because of high efficiencies attained throughout the entire power range, the SKY77761-11 delivers unsurpassed talk-time advantages. The SKY77761-11 meets the stringent spectral linearity requirements of High Speed Downlink Packet Access (HSDPA), and High Speed Uplink Packet Access (HSUPA) data transmission with high power added efficiency. An integrated directional coupler eliminates the need for any external coupler. The Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all amplifier active circuitry, including input and interstage matching circuits. The silicon CMOS support die, providing precision biasing for...
