摘要
随着新技术在无线通讯的应用,对高频产品的传输信号和射频功率等提出了更高的要求,无源互调(PIM)成为限制系统容量的重要因素。文章针对一种高频PCB产品出现PIM异常而影响射频信号,通过不同的对比试验分析和验证,找到影响PIM偏移的原因和控制方法。
With the new technology applied in the wireless communication industry, it needs higber requirements on the transmission signal and RF power of the high-frequency products and the passive intermodulation （PIM） becomes an important factor of capacity of the system limit. In this paper, a high-frequency PCB products PIM anomaly appears to affect the RF signal through comparative test analysis and verification, to find the causes and control methods that affect PIM exception.
