无线网络交换机射频传导抗扰度对策研究

Countermeasure Study on RF Conducted Immunity of Wireless Network Switch

无线网络交换机一般用于基站环境,外界干扰信号容易通过信号线或外壳耦合到无线网络交换机,影响其正常工作。文中基于以上情况,分析介绍GR-1089-CORE射频传导抗扰度的测试原理和EUT在试验中出现的问题,然后从接口滤波器的选取及安装电路设计两方面出发,进一步提出一系列的对策措施,增强无线网络交换机的射频传导抗干扰能力。

Wireless network switch is generally used for base station environment.External interference signal affects its normal work through the signal line or shell.Based on the above situation,The paper analyses the test principle of RF conducted immunity in GR-1089-CORE.The problem is also discussed in the test.And a series of countermeasures are put forward to strengthen the conducted immunity capability of wireless network switch from the filter selection and circuit design two-pronged approach.
