摘要: 本文提出了兩種改進(jìn)寬頻帶大功率速調(diào)管等激勵(lì)功率-頻率特性的方法。其一是在行波管推動(dòng)級(jí)和速調(diào)管間加入具有一定衰減特性的帶通濾波器,使之與速調(diào)管增益-頻率特性互補(bǔ),以獲得所要求的等激勵(lì)增益-頻率特性;另一是在輸入腔外接電抗元件,用來改變輸入腔的諧振頻率f0和QL ,以達(dá)到改善速調(diào)管增益-頻率特性的目的。

Abstract: Two methods for improving the equidriving power-frequency characteristics of broadband high power klystrons are presented. One is that a comb-line bandpass filter with attenuation properties is inserted between the TWT driver and the klystron for compensating the gain-frequency characteristics of the klystron to get the required equidriving gain-frequency characteristics. The other is that a reactive element is connected with the input cavity to change its resonance frequency f0 and QL and then to improve the gain-frequency characteristics of the klystron. -
