中文摘要:
      该文设计了一款电容加载结构的小型化腔体滤波器。谐振器端头采用圆盘结构的电容加载,并使用四氟乙烯材料在谐振杆中间位置进行支撑加固;计算过程中,为三维电磁模型添加了集总端口,与电路模型联合仿真进行参数优化。通过三维电磁环境下的功率容量分析,该滤波器满足大功率指标要求。
英文摘要:
      A compact cavity filter with capacity loaded structure is designed in this paper. A disc shape end of the resonator is adopted to realize capacity loading, and Teflon support structure is used to reinforce the resonant post. In the calculation process, the lumped ports are added into the 3D electromagnetism model, and then the co simulation with circuit model can optimize parameters more efficient. The power capacity analysis is carried out under 3D electromagnetic environment, and the results show that the filter meets the requirements of high power index.
