| Abstract: | The idealized model of tuned power amplifier of the class E is that the collector current fall time is zero. The purpose of the paper is to analyze the equations governing the operation of the amplifier when the collector current fall time is nonzero. Under the state of optimum operation of the amplifier, the following basic amplifier parameters are determined: the waveforms of the collector current, the collector-to-emitter voltage, the instantaneous power dissipated in the transistor, the collector efficiency, and the values of the load-network components. |
