Abstract

In this paper a new functional model for the class-AB solid-state bipolar power amplifiers is presented. The model, based on a Fourier sine-series is simple and can provide closed-form expressions for the intermodulation products resulting from exciting the power amplifier by a multisinusoidal signal. The special case of a two-tone equal-amplitude signal is considered in detail. The proposed model can be used to build a database for the intermodulation performance of the class-AB bipolar SSPAs excited by a multisinusoidal signal.
