Abstract :
Class E amplifier theoretical efficiency is 100%, but the practical results at 10 GHz are much lower. In this paper, we propose a Class E amplifier that uses a photoswitch as active device instead of a transistor. The photoswitch opening and closing is controlled by light pulses. We used Silvaco software to do simulations of such an amplifier. Using this design, our best simulated efficiency at 10 GHz is 62.5%
