Simulation and design of a Class E power amplifier

Class E switching-mode tuned power amplifier offers high efficiency at high frequencies. Class E power amplifier concept, introduced by Sokal, is not defined by a special topology. The most simple topology for class E power amplifier consists in a single switch device that operate at carrier frequency of the output signal and a load network that must extract only a single spectral frequency component. The load network consists in a capacitor shunting the switch device and a series-tuned output circuit. To derive the basic equations for class E amplifier we use Fourier series techniques. These equations are implemented in Matlab with a friendly interface. This implementation and this interface can be a very useful tool for students that are interested in class E operation and also a good tool for class E circuit design. In this paper you can find a description of class E power amplifier with functional equations.
