“…This model provides a convenient way for changing the sharpness of the knee while maintaining linearity for small inputs. In [11] a modified version of the model of [8] has been presented. The proposed model in [11] is a two-parameter model that caters for the nonlinear behavior observed at relatively low input levels in solidstate power amplifiers.…”

“…This model is formed of one portion and caters for nonlinear characteristics starting with a linear part, for relatively low inputs, and followed by a nonlinear part at relatively large inputs. Unfortunately, the models proposed in [5,8,11,21,23,28] can not yield closed-form expressions for the amplitudes of the output intermodulation products resulting from a multisinusoidal input. Thus, recourse to numerical solutions using computer aided tools is necessary.…”

Simple single-parameter models are presented for the instantaneous characteristics of nonlinear electronic systems. The models can easily provide closed-form expressions, in terms of the ordinary Bessel functions, for the amplitudes of the output components of the nonlinear systems excited by multisinusoidal signals. Moreover, being a single-parameter model, the nonlinear electronic circuit can be easily characterized using a set of measured data for the variation of the relative output third-order intermodulation over an appropriate range of input tone amplitudes of a two-tone equal-amplitude input signal.

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.
