Maximum Output Power of Class E Amplifier for a Given Transistor, Operating Frequency, and DC Supply Voltage

This paper analyzes maximum output power of class E amplifier with arbitrary transistor. It is important to estimate maximum output power of class E amplifier when a specification of transistor is given. In this paper, values of circuit parameters that gives maximum output power for given operating frequency, dc supply voltage, and output capacitance of the transistor are calculated. This paper presents scheme to calculate circuit parameters that maximum output power in this condition. Finally, some example calculations are shown when this scheme was applied to some actual power MOSFET transistors. Keyword: Class E amplifier, Maximum output power, Transistor, Sub class E operation
