【摘要】 无源互调(Passive Intermodulation,PIM),一直是高功率微波通信中的一个技术难题。本文主要介绍了PIM的一般研究模型,行波测试系统和驻波测试系统,以及利用测试技术来区分电流源模型和电压源模型、"降阻"模型和"升阻"模型、E指数模型和双曲正切模型等,为无源互调的研究、测试提供一定参考。更多还原

【Abstract】 Passive Intermodulation(Passive Intermodulation, PIM), has been a technical problem in the high power microwave communication system. This paper mainly introduces the general research model of PIM, travelling wave and standing wave testing system, testing methods used to discrimination different models, including the current source model and the voltage source model, the "Increasing-Resistance" model and "Decreasing-Resistance" model and two matheatical models. It provides certain reference for the research and testing of PIM.更多还原
