This paper describes advantages and characteristics of a class E power amplifier when used in a polar transmitter system. Basic principles of class E operation and information about different nonlinearities are given. Also, modifying the transistor model for switch-mode use is discussed briefly. A 1...
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 Si...
