  Abstract

In this paper, 3-way Doherty power amplifier with W-CDMA is designed and implemented for improvement of efficiency and linearity. It uses class F and Doherty technique for high efficiency and linearity. Peaking amplifiers proposed class F for improvement of efficiency and using adjustment of bias point for improvement of linearity simultaneously. Power amplifier's measurement result using proposed technique in W-CDMA 4FA, average output power 20 W shows ACLR -41.17 ㏈c @ 5 ㎒ offset, and efficiency of 31.2 %
