摘要
Abstract
Different from conventional high power high efficiency space TWTs,the high efficiency dualband TWTs cover both Ka and Q bands.In this research,a high frequency circuit is designed to satisfy Ka-band and Q-band,and the high-frequency characteristics in these bands are simulated by using MTSS software.In the calculation of beam wave interaction,the reason of back wave oscillation (BWO) in traditional pitch distribution structure is analyzed.On this basis,a new pitch distribution structure is proposed to suppress the BWO.In order to improve the nonlinear distortion of TWT,a gradual structure is added in the phase reduction part of the output section.Nonlinear distortion of dual-band TWTs is studied initially.关键词
