The SKY77163 AutoSmart? PAM is a fully matched, 8-pin surface mount module developed for CDMA/AMPS and Wireless Local Loop applications. AutoSmart? power amplifier 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 CDMA system requirements. The result 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 is more than adequate for RF access probe and discontinuous transmission operation. See Product Summary below for more details. Please note: SKY77163-11 is being discontinued and is not recommended for new design.
