CAD tool for a class E tuned power amplifier design

The concept of “class E” was introduced by N. O. Sokal and A. D. Sokal, offering a new concept of high efficiency power amplifiers. Class E power amplifier is not defined by a special topology. The chosen circuit is a tuned amplifier, consisting of a single switch and a load network. The load network configuration consists of the shunt capacitance, series inductance, and series filter tuned to the fundamental frequency to provide a high level of harmonic suppression. This working class have the advantage of their design simplicity and high efficiency operation. Using the basic equations for class E amplifier, a user friendly graphic interface was implemented. This interface is a useful tool for simulations and design. We can see various waveforms from the circuit and she permit to estimate the real values of circuit components. Also the interface calculate the power efficiency, power consumption for different loads, etc.
