Abstract :
Multifunctional RF front ends need to transmit different types of signals while maintaining efficiency and signal quality, we show that switched mode class-E power amplifiers can achieve high efficiency at RF frequency. In this paper, a 20W class-E power amplifier has been designed using MRF21030. The input match network and output network has been simulated carefully and the output efficiency of power amplifier is 63%. Further more, the effect of Vdd and input power have also been analyzed.
