摘要 寻求频带更宽、输出功率更大、体积更小的螺旋线行波管一直是研制工作的目标,二次谐波是影响宽带行波管工作的重要因素,本文对不同形式介质加载的螺旋线慢波结构进行了模拟,并对其中色散曲线最为平坦的钮销慢波结构进行了一维大信号模拟,证明改变螺距或夹持介质形状可有效展宽带宽、降低二次谐波功率。 To make the helix TWT with wide band, high fundamental wave power output, low harmonic power output and small size is the aim of research projects. This paper describes the simulation results for TWTs with different dielectric loading and the helix pitch changes. The results show that the changes in dielectric shape and pitch can make TWT wider in bandwidth and reduce the power output of the second harmonic.
