摘要

军用射频和微波放大系统对可靠性要求较高，采用模块化结构实现。本文对两级4并联模块的超高频放大系统进行了仿真。为了更好地组合网络(Gysel和/或分支耦合器)，研究了所提出的系统。此外，它还严格研究了由于一个或多个模块故障而导致的性能下降。通过关闭一个或多个模块来模拟系统故障分析。结果用散射参数和系统输出功率退化与失效模块数量的关系来表示。利用微波办公软件对系统进行了设计和故障分析。

Performance Evaluation and Failure Analysis of Modular Power Amplifier with Gysel and Branch Coupler Network

Military radio frequency (RF) and microwave amplifier system requires high level of reliability so it is implemented in modular structure. In this paper, Ultra high frequency (UHF) amplifier system with two levels and 4 parallel modules is simulated. The proposed system is investigated for better combining network (Gysel and/or Branch coupler). Also it is critically investigated for performance degradation due to failure in one module or more. Analysis of system failure is simulated by turning off one module or more. The results are represented in terms of Scattering parameters and degradation of the system output power versus number of failed modules. Microwave office software have been used for the design and failure analysis of the proposed system.
