Abstract

In this work, the phase compensation techniques by means of self-biasing control and an additional tuning capacitor for polar modulated tri-band Class-E power amplifier is proposed. The tri-band power amplifier operating at 2.3∼2.7/3.3∼3.8/5.1∼5.8 GHz for WLAN and WiMAX applications adjusts low loss Micro-Electro-Mechanical-Systems (MEMS) switches to select the matching networks. The improvement of phase distortion and system relative constellation error (RCE) is 36.4° and 8.9dB, respectively. Simulation results shows that the maximum power-added efficiency (PAE) of 34.9%, drain efficiency of 37.3%, and output power of 18.8dBm from 2.8V supply can be achieved in 0.18μm CMOS Technology.
