5.6 WCDMA PA IC
Description
The SKY7776XX 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 stained
throughout the entire power range, the SKY7776X delivers unsurpassed talk-time advantages. The SKY7776X
meets the stringent spectral linearity requirements of High Speed Downlink Packet Access(HSDPA).High Speed
Uplink Access (HSUPA),and long Term Evolution (LTE)data transmission with high power added efficiency. An
integrated directional coupler eliminates the need for any external coupler.
