Product Summary

The SKY77255-11 is a Power Amplifier Module (PAM). The SKY77255-11 is a fully matched, 10-pad, surface mount module developed for Time Division Synchronous Code Division Multiple Access (TD-SCDMA)applications. Skyworks’SKY77255-11 also supports TD-SCDMA multi-slot operation. This small and efficient module packs full 1880–1920 MHz and 2010-2025 MHz bandwidth coverage into a single compact package. The PAM meets the stringent spectral linearity requirements of TD-SCDMA transmission, with high power added efficiency for power output of up to 28 dBm. The applications of the SKY77255-11 includes TD-SCDMA handsets.
