摘要

摘要: 该文给出了一种三段式互作用结构谐波倍增回旋行波管放大器互作用电路的理论设计过程。利用线性理论研究竞争模式的起振条件，选取保证工作模式稳定的工作参数。利用自洽非线性理论研究其饱和输出性能。计算表明，在100kV，25A，速度比1.0以及速度零散5%的电子注推动下，在34.6GHz频率可获得饱和输出功率540kW，效率21.6%，增益58dB和约4.5%的3dB带宽。

Abstract: In this paper, the design procedure of a harmonic multiplying Gyro-TWT with three stage interaction circuits is presented. The starting oscillation condition of competing modes is studied with linear theory to select the working parameters for keeping the stability of working mode. The saturated output performance of the working mode is discussed by using a consistent non-linear theory. Based on large signal numerical analysis, a saturated peak power of 540kW with an efficiency of 21.6%, a gain of 58dB, and a 3dB bandwidth of 4.5% is predicted for the gyro-TWT driven by 100kV, 25A electron beam with a velocity ratio of 1.0 and velocity spread 5% at 34.6GHz.
