Abstract: In this paper the class E power amplifier is described and its analysis for the finite choke inductor value is given. The optimum values of the circuit elements for minimizing transistor losses are calculated for several values of the choke inductor. Then, the frequency analysis of the optimal circuit is performed and computer results from analysis are presented. The class E power amplifier can be used as an amplitude modulator, so the analysis is performed and the amplitude modulation characteristics are also presented.
Key words: E power amplifier, transistor losses, ampltide modulator.
