摘要
基于耦合矩阵综合的方法,辅以数值优化,可以实现不同期望目标的双通带滤波器,设计过程清晰、便捷。基于前期的分析计算,使设计后期的仿真、优化及调试工作量明显减少。而交叉耦合的引入,能在特定频点引入传输零点,大幅提高了滤波器的性能,从而使滤波器的设计快速且准确。通过实例设计和仿真,验证了该计算方法的正确性,并对结果进行了讨论,对高性能双通带滤波器设计具有重要的参考价值。
The method based on coupling matrix and assisted by numerical optimization, could achieve dual-band filters with different expected objectives, and the entire design process is clear and convenient. The early-day calculation based on mathematical analysis clearly reduces the workload of simulation, optimization and debugging in the later-on design process. The cross-coupling design could introduce the certain transmission zeros at a specific frequency, thus greatly improving the performance of the filter and making the filter design faster and more accurate. The example design and simulation indicate the correctness of the theoretical calculation. Meanwhile, the experiment results are discussed as well. All this is of important reference value for the design of high-performance dual-band filter.
