摘　　要：该文主要介绍了利用渐进空间映射法优化设计同轴腔体交叉耦合滤波器的方法。在HFSS和ADS软件中分别建立了滤波器的结构模型和等效电路模型,在ADS软件中进行了反映模型参数映射关系的参数提取,提取的参数精度高并且速度快。整个设计过程仅需进行5次精确模型仿真与5次粗糙模型仿真,即可优化得到一个十分接近理想响应的高性能四腔交叉耦合滤波器。从而证明了此优化方法的可行,高效。This paper introduces the method of using aggressive space mapping technique to optimize the coaxial cavity cross-coupled filter.In the HFSS and ADS software,the structure model and the equivalent circuit model of the filter are established respectively,parameter extraction that reflected the mapping relationship was carried out in the ADS software,the extracted parameters is high accuracy and very fast.Throughout the design process only needed five accurate model simulations and five coarse model simulations,optimization can be very close to the ideal response of a high-performance four order cross-coupled filter.It is proved that this optimization method is feasible and efficient.
