| 摘 要： | 提出一种基于渐进空间映射算法(ASM)与遗传算法(GA)相结合的I/O端口不等长相移效应的滤波器快速调试方法。渐进空间映射算法能够准确预测精细模型的调试方向与幅度,遗传算法能够准确快速得到I/O端口的相移效应,并且通过柯西法提取粗糙模型。基于有限元的全波电磁仿真软件HFSS,建立精细模型,粗糙模型参数即等效电路参数,则由去除I/O端口处相移效应后的S参数获得。利用该方法对六阶交叉耦合滤波器进行调试,经过几步迭代即可使滤波器满足所要求的响应指标,验证了该调试方法的正确性和有效性。

| Abstract: | A novel tuning method based on aggressive space mapping (ASM) and genetic algorithm (GA) is presented in this paper. The method is applied to microwave filters with different phase shift effects at I/O ports. The tuning direction and magnitude are predicted by ASM. The phase shift effect can be calculated by GA, then the coarse model parameters are extracted by the Cauchy method. The fine model is constructed by the commercial FEM simulation software HFSS, and the coarse model is the equivalent circuit. A sixth order cross-coupled filter tuning example is used to verify the new method and the validity of the method is proved. The filter meets specifications less than four iterations. |
