摘要

本文提出了一种利用单指数啁啾测量获得功率放大器行为模型的技术。得到的模型等于记忆多项式。然而，该过程依赖于一个特殊的激励，使正交提取，使识别快速和可靠。该模型对不同的激励有较好的近似结果，可用于功率放大器谐波频率响应的近距离检测。

RF PA modeling with one chirp measurement

In this paper we present a technique for obtaining a behavioral model for a power amplifier using a single exponential chirp measurement. The obtained model is equal to the memory polynomial. However, the process relies on a particular excitation that enables orthogonal extraction, making the identification quick and reliable. The model presents good approximation results for different excitations, and can be used for close inspection of the harmonic frequency responses of a power amplifier.
