提高宽带毫米波行波管效率研究

摘要

针对影响宽带毫米波行波管效率的主要因素,对提高行波管效率的相关实用化技术进行了研究.通过螺旋线线路渐变技术、降低高频损耗、多级降压收集极三个方面的研究,使现有某一宽带毫米波行波管总效率由原来的10％提高到20％以上.%The main factors which influence the efficiency of millimeter wave TWTs have been analyzed. And some practical technology of increasing TWTs' efficiency was proposed which includes: helix pitch tapering, circuit loss reducing and multi-stage collector optimizing. The overall efficiency of one wideband millimeter wave TWT is enhanced from 10% to 20%.
