摘要: 该文设计了工作于高阶横磁TM310模式单间隙封闭圆柱同轴腔。在输出矩形波导内设计了横向电感滤波膜片的新型结构。用模拟场分析法计算了腔内6个漂移管中心处间隙阻抗平均值的频率特性。模拟和计算发现，该结构模式输出回路的间隙阻抗平均值随频率的变化出现双峰曲线。这表明，采用滤波膜片波导的输出带宽比采用空波导情形的带宽有明显的增加。Abstract: Single gap close coaxial resonator cavity with high order TM310 mode is designed. A new structure of output rectangular waveguide with the transverse inductance filter diaphragms is also designed. The average gap impedance variation with the frequency at the six drift tube center in the cavity are simulated and calculated. It is found that the curve of average gap impedance on frequency have two peaks, it indicates that the relative bandwidth of this output circuit is larger than that of empty waveguide.
