POI无源混合互调干扰分析研究

摘要

POI hybrid passive intermodulation seriously affects the communication system capacity and quality when communication system and device are progressing toward broadband, multi-port, multi-channel, and high power. The paper first introduced the structure of POI system, then systematically combed through and analyzed the occurring factors of POI passive hybrid intermodulation, and listed actual cases and solutions.%通信系统和器件向着宽带化、多端口、多信道、大功率等方向发展，POI无源混合互调严重影响通信系统的容量和质量，首先介绍了POI系统的结构组成，接着对POI无源混合互调产生的因素进行了系统的梳理和分析，并且列举出了实际案例和解决思路。
