MT2000短波发射机谐波滤波单元(以下通称谐波滤波单元)在短波发射系统有谐波滤波、阻抗匹配以及功率监测等重要作用。谐波滤波单元是连接发射机和天馈线系统的桥梁。谐波滤波单元的故障会直接导致整个发射系统的瘫痪。因此维护好谐波滤波单元是保证发射系统正常运行必不可少的一个重要环节。下面是我根据这几年工作实践累积的关于谐波滤波单元故障以及技术维护方面的经验总结。
MT2000 short-wave transmitter harmonic filter unit (hereinafter referred to as harmonic filter unit) in the short-wave transmission system has harmonic filtering, impedance matching and power monitoring and other important role. Harmonic filter unit is connected to the transmitter and antenna feeder system bridge. Harmonic filtering unit failure will directly lead to paralysis of the entire launch system. Therefore, to maintain the harmonic filter unit is essential to ensure the normal operation of the launch system is an important part. The following is my experience based on the past few years of work on the harmonic filter unit failure and technical maintenance experience.
