摘要

本文将谐波平衡和包络暂态分析工具应用于潜在不稳定功率放大器的分析和设计。通过分岔检测确定了不稳定行为的范围，并研究了奇模不稳定性对互调失真的影响。放大器的稳定使用分岔控制的概念。此外，提出了一种放大器稳定的反馈结构，并将结果与以往基于电阻负载的方法进行了比较。该技术已应用于一台4ghz微波放大器。

Analysis and stabilization tools for microwave amplifiers

In this paper, harmonic balance and envelope-transient tools are applied to the analysis and design of potentially unstable power amplifiers. The ranges of unstable behaviour are determined through bifurcation detection and the effects of odd-mode instability on the intermodulation distortion are investigated. The amplifier is stabilized using concepts from bifurcation control. Additionally, a feedback configuration for the amplifier stabilization is proposed and the results are compared with those obtained with previous methods, based on resistive loading. The techniques have been applied to a 4 GHz microwave amplifier.
