摘　　要：分析了广义切比雪夫函数和耦合矩阵综合,提出综合广义切比雪夫函数和阶跃阻抗谐振器设计小型化滤波器。采用同轴阶跃阻抗谐振器设计了中心频率为2.14GHz,带宽为60MHz的交叉耦合滤波器,同时分析了同轴阶跃阻抗谐振器耦合实现方法和电路形式,证明了该方法的可行性,并获得很好的试验结果。同交叉耦合滤波器比较,设计的滤波器体积减小了30%。The generalized Chebyshev od of miniaturization filter by synthesizing coupling filter with center frequency of 2. ization of the coupling method and circuit tained very good experimental results. Th function and coupling matrix synthesis is analyzed, and the design meth with network forms and step-impedance resonator is presented. A cross14GHz and bandwidth of 60 MHz is designed, and an analysis of the real-form is given. This design proves the feasibility of the method and obe designed filter reduces the volume of 30%.
