In this paper, distortion in the output envelope of AM modulated a class E RF power amplifier with a nonlinear capacitance with the grading coefficient m = 0.5 is analyzed. The calculation of output amplitude incorporates the influence of power loss versus dc supply voltage. Derivation of half cycle output voltage waveform is done with incorporating output amplitude as a function of dc supply voltage of the class E amplifier. The calculation was performed with Mathcad programming.
