摘　　要：在行波管整管性能中,波导与慢波结构的阻抗匹配具有关键作用。已知慢波结构,设计了输入/输出过渡波导,过渡波导结构的S参数满足设计要求。采用两节腔慢波结构加载波导,模拟分析了无电子注作用时高频波的传输特性,分析得到引起衰减的主要因素并判定输入/输出波导与慢波结构的阻抗匹配状态良好。Impedance matching between waveguide and slow- wave structure is significant for performances of travelling wave tube. A ladder transition waveguide is designed for the coupled cavity Travelling Wave Tube （TWT）. Its parameters meet design requirement. The transmission parameters without electron beam of two cavities loaded waveguide are simulated and were analyzed. The good matching between slow- wave structure and waveguide is demonstrated.
