GSM900 DCS1800双波段功率放大器演示板的说明

Dual band GSM900 and DCS1800 (or DCS1900) phone design puts a real challenge on Power Amplifier function which needs to operate in two frequencies while providing appropriate isolation and control for each frequency.

This application note describes the dual band demoboard that we have developed based on two single band Power Amplifier ICs: MRFIC0919 and MRFIC1819, plus a dedicated

control IC: MC33170 (product of On Semiconductor).
