Design equations for satisfying sub-optimum operating condition (i.e., only the ZVS condition) of class E amplifier with a linear shunt capacitance at the duty cycle D = 0.5 are derived. By exploiting sub-optimum class E operation, various amplifier parameters such as operating frequency, output power, and load resistance range can be set as design specifications. An example of a design procedure of the class E amplifier is given. The theoretical results were verified with PSpice simulation.
