研究了匹配均匀微带线上的无源互调(PIM)源。对不同等级铜箔涂覆的印制电路板上的导线进行了PIM测量和扫描电子显微镜分析，结果表明印刷传输线上的PIM源具有沿信号路径分布的非局域性。铜箔的质量和表面粗糙度是影响低损耗聚四氟乙烯介质基板上微带线离子注入性能的关键因素。
The sources of passive intermodulation (PIM) on matched uniform microstrip lines have been investigated. The results of PIM measurements and SEM analysis of the conductor traces fabricated on the PCB laminates coated by copper foils of different grades suggest that PIM sources on the printed transmission lines are of non-local nature being distributed along the signal path. Quality of the copper foil and roughness of its surface proved to critically affect PIM performance of the microstrip lines on the low loss PTFE based dielectric substrates.
