DESIGN OF CROSS-COUPLED RESONATOR FILTERS WITH PARALLEL RESONANCE CIRCUITS

摘要

A method to design a cross-coupled resonator filter with parallel resonance circuits is presented, which includes the selection of a circuit model, introduces a scaling factor and a bandwidth condition, and calculates the values of the coupling and resonance admittances of the circuit model by a coupling matrix derived from the given transfer function. Finally, an example is given to illustrate the design procedure. The simulation results validate the proposed design procedure.
