摘要
本文提出了两种改进宽频带大功率速调管等激励功率-频率特性的方法。其一是在行波管推动级和速调管间加入具有一定衰减特性的带通滤波器,使之与速调管增益-频率特性互补,以获得所要求的等激励增益-频率特性;另一是在输入腔外接—电抗元件,用来改变输入腔的谐振频率f_0和Q_L ,以达到改善速调管增益-频率特性的目的。
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.
