摘　　要：输能系统是影响高频率毫米波行波管高效率输出的关键因素,为研制V波段30 W空间行波管,拓展V波段输能系统的带宽和提升与高频慢波系统的匹配特性,利用传输理论分析和仿真软件优化两种方式改善限制V波段螺旋线行波管宽带驻波比较高的问题,并根据公式推导和CST软件仿真结果开展工艺试验,验证新结构的大螺距绕线方案对改变传输匹配特性是否有效,最终证明了在57~63 GHz工作频带内驻波系数小于1.4,满足V波段空间行波管的使用需求。Energy Transmission System(ETS)is a key factor affecting the high efficiency of Millimeter Traveling Wave Tubes(TWTs)above V band frequency.In order to develop V-band 30 W Space-TWTs and improve the bandwidth and matching characteristics of Slow Wave System(SWS)and ETS,the Transmission Matrix(TM)Theory and Simulation Optimizer are integrated with fabrication test the new ETS structure of Helix Large Pitching whether to improve the matching with SWS.Based on TM formula derivation and CST software simulation,the new type of V-band ETS was fabricated to meet the Space-TWTs demands with Voltage Standing Wave Ratio(VSWR)less than 1.4 over the V-band frequency range between 57 to 63 GHz.
