耦合腔行波管中的切断匹配负载的设计和测量

介质谐振损耗腔用作耦合腔行波管切断处匹配负载，国内外已进入实用阶段，本文就此进行讨论，并给出了该介质腔谐振频率，介电常数，品质因素和损耗角的计算及测量方法，在研制一只Ｃ波段５０ｋＷ耦合的腔行波管中，理论与实则吻合，表明了本文理论分析和测量方法的有效性和可行性。

On the Study of Maching Terminals and Seversin Coupled -Cavity TWT

This paper discussed the resonant loss dielectrical cavity used for matching terminals and severs in coupled cavity TWT, which has been put into practice in our research work. The methods of calculation and measurement for resonant frequency,dielectrical constant,quality factor and loss tangent of the varierty of dielectrical cavity were given. It has been verified in developing aC-band 50KW coupled-cavity TWT that the theoretical calculation data were in good agreementwith test results,so that the validity and feasibility of this analysis and measurement method wereshown.
