摘　　要：为打破空间行波管在轨单机专用的传统工作模式,最大限度地利用分布不均的通讯流量,实现卫星宽带交互式服务,可调空间行波管的研制应运而生。本文利用CST、MTSS软件对其电子枪、高频慢波系统、收集极等结构进行模拟仿真,研制出的样管实现了Ka波段1 GHz带宽内100~50 W功率可调:饱和增益≥56 dB@100 W、≥43 dB@50 W;总效率≥61%@100 W、≥54%@50 W。模拟设计结果与实测结果符合性大于90%,基本满足技术要求。In order to break the traditional dedicated working mode of on-orbit single machine,make full use of uneven communication flow and realize satellite broadband interactive service,power flexible space TWTs are developed.In this work,CST and MTSS software are used to simulate the structures of electron gun,high frequency slow wave system and collector.The developed TWT has realized 100~50 W adjustable power in Ka-band with 1 GHz bandwidth.The saturation gains at 100 W and 50 W are greater than 56 dB and 43 dB,respectively;and the total efficiencies at 100 W and 50 W are greater than 61%and 54%,respectively.The simulation result is more than 90%in accordance with the measured one,which basically meets the technical requirements.
