Structureless modeling of power amplifiers accounting for inertial properties

L. I. Averina, V. D. Shutov, R. A. Rybalkin

Abstract


The paper considers various structureless inertial non-linear models of power amplifiers and methods of their identification. Based on polynomial model with memory and Volterra model the influence of different kinds of input signals, their bandwidth and average power on precision of power amplifier modeling and complexity of model implementation.
