摘要

传统上，泰勒级数模型仅用于小信号或轻度非线性情况。提出了一种基于多变量非线性一阶泰勒展开式和插值的微波功率放大器行为模型。该模型是为宽带、高动态刺激驱动的pa量身定制的。将该模型与其他几种具有代表性的行为模型进行了理论比较。讨论了为验证目的而设计的数学模拟实验。

A new pa behavioral model based on the linearization of multivariable nonlinearities and interpolation

Traditionally, Taylor series models are only used under small signal or mildly nonlinear regimes. In this paper, a new behavioral model for microwave power amplifiers (PAs) based on first order Taylor expansion of multivariable nonlinearities and interpolation is proposed. The model is tailored for PAs driven by wideband, highly dynamic stimuli. Theoretical comparisons are made between this model and several other representative behavioral models. A mathematical simulation experiment designed for validation purposes is discussed.
