地面站用行波管本节介绍连续波大功率行波管的现状。可以说,连续波大功率行波管是当今发展最快的微波器件之一,它的迅速发展是同卫生通信紧密相关的。目前,这类行波管的研究方向是:提高输出功率、展宽放大频带、开发新的波段。当连续波行波管向着更高功率前进的时候,特别是在频率较高的波段,遇到的一个大问题就是如何把大量的热能从慢波线导出。随着不断对结构和技术性能进行的改进,连续波大功率行波管的型号不断增加,目前已超过300种。
Traveling wave tube for ground station This section describes the current status of continuous wave high power traveling wave tube. It can be said that continuous wave high-power TWT is one of the fastest growing microwave devices in the world. Its rapid development is closely related to health communications. At present, the research directions of such TWTs are: increasing output power, broadening and amplifying frequency bands and developing new wavebands. As CWWRs move towards higher power, especially in the higher frequency bands, one of the major problems encountered is how to export a large amount of heat away from the SWW. With the continuous improvement of the structure and technical performance, continuous wave high-power traveling wave tube models continue to increase, now has more than 300 kinds.
