摘要(Abstract)：

通过检查分析一次高频收发信机频报"3 dB告警"又可以自动恢复的异常现象,找出了高频通道耦合电容器的缺陷,为高频通道的缺陷处理提供经验借鉴。
The defects are found in high-frequency carrier channel coupling capacitor through the examination and analysis on the abnormal automatic recovery after frequent 3 dB alarms from primary high-frequency transceiver,and it can serve as a reference for defect treatment of high-frequency channel.
