| Abstract: | The generalized Chebyshev function and coupling matrix synthesis is analyzed,and the design method of miniaturization filter by synthesizing with network forms and step-impedance resonator is presented. A cross-coupling filter with center frequency of 2.14GHz and bandwidth of 60 MHz is designed,and an analysis of the realization of the coupling method and circuit form is given. This design proves the feasibility of the method and obtained very good experimental results. The designed filter reduces the volum... |
