行波管发射机原理及调试

Principle and Debugging of Traveling Wave Tube Transmitters

行波管发射机故障率相对较高,为提高发射机可靠性,以关键器件行波管为关注对象,对行波管发射机的工作原理进行介绍。描述了行波管类发射机在调试时涉及的输出功率和相位一致性等主要参数的调试方法,并介绍了行波管发射机在调试过程中可能遇到的发射机自激和螺旋线电流保护等常见问题的处理方法,以供相关人员参考。

The failure rate of TWT transmitter is relatively high.In order to improve the reliability of the transmitter,the working principle of TWT transmitter is introduced with emphasis on the key device TWT.This paper describes the debugging methods of main parameters such as output power and phase consistency involved in the debugging of TWT transmitters,and introduces the solutions to common problems such as transmitter self-excitation and spiral current protection that may be encountered in the debugging process of TWT transmitters,for the reference of relevant personnel.
