AutoSmart? Power Amplifier Module for WCDMA (1710-1755 MHz)

SKY77177 AutoSmart? PAM, a fully matched 8-pin surface mount module developed for WCDMA handsets, packs full 17101755 MHz bandwidth coverage into a single compact package while meeting stringent spectral linearity requirements of WCDMA with high PAE for power output of up to 28 dBm.AutoSmart? PA technology internally adjusts the RF transistor bias level throughout the dynamic operating range to minimize battery current consumption and ensure sufficient linear performance to meet WCDMA system requirements. The result of SKY77177 is a significant savings in average battery current without the complications of a system-supplied mode function signal or analog bias control. AutoSmart? response time of SKY77177 is more than adequate for RF access probe and discontinuous transmission operation.
