Abstract :
The class DE RF power amplifier is analysed in the normalised effective load impedance plane. The conditions for zero voltage switching (ZVS) and class E switching transitions are obtained. A proposed matching network allows ZVS operation for any resistive load. Class DE transistor utilisation approaches that of class D
