Abstract :
A mathematical expression of the nonlinear distortion of a power amplifier is studied, taking into consideration the effect of the even-order distortion component at base-band. In order to asses the feasibility of the mathematical expression, nonlinear distortion characteristics are investigated by numerical calculation for some test signals. Important characteristics such its the memory effect are explained with the mathematical model.
