电子系统EMC设计中的同轴线接地方法研究
|
摘要
本文从分析电子系统中同轴线信号传输原理入手,分析了同轴线传输在不同频率下的传输特性,详细研究了不同接地方式对不同传输信号的影响,阐明了发生机理,明确了不同传输条件下电子系统中同轴线的接地方法,同时探讨了低阻抗地线的关键技术点和设计方法,可为设计电子系统中同轴线在不同电磁环境下的接地方案提供借鉴。
After analying the transmissing principle of the electronic system using coaxial cable, this article studied the grounding way of the coaxial cable in electronic sysytem, analying the influencement of the different grounding way, and giving the correct way of the EMC grounding for coaxial cable and electronic system in different occasions, and wish this paper can give some benefit to the people who will design the electronic system using coaxial cable in order to have good electromagnetic performance.
