摘要: 采用高次模同轴输出腔结构和双间隙耦合谐振腔电路结构是提高速调管频率、功率和带宽的两个重要方式。将这两种电路形式相结合，利用等效电路法推导了滤波器加载双间隙耦合输出回路的间隙阻抗实部计算公式。通过等效电路分析和3维电磁场计算软件模拟，研究了降低高次模式双间隙耦合输出回路外观品质因数的方法。最终设计加载滤波器使得输出回路模型带宽达到9.7%。Abstract: The high-order mode coaxial cavity output circuit and the double-gap coupled cavity circuit are important for high frequency, high power and broadband klystrons. In this study, the two structures mentioned above are combined. The real part of the gap impedance of the filter-loaded double-gap output cavity is derived according to the equivalent circuit theory. In addition, the method for reducing the external quality factor of high-order mode double-gap output circuit is discussed on the basis of the microwave principle and simulation. The output circuit loaded with the designed filter has a bandwidth of 9.7%.
