C波段大功率多注速调管高频特性研究

Study of High Frequency Part in C-Band High Power Klystron

在速调管的制管过程中,加大谐振腔尺寸及调整漂移管间距两种手段都能将原高端谐振腔工作频率调整到低端工作频率,但不同的调整方法对腔体特性阻抗的影响不同。本文通过对C波段大功率多组多注速调管的研制,分析对比了这两种方法对腔体特性阻抗及输出特性的影响。同时,对一定的工艺手段抑制测试振荡的方法进行了探讨。

Cavity size enlargement and the distance of drift tube adjustment can both depress the working frequency of klystron.However different ways make different influence on cavity characteristic impedance.In this paper,the test results of the two ways have been compared during the development of C-band High Power Klystron.At last technology of high-frequency oscillation suppression was also discussed.
