摘要
Abstract
The coupling coefficientwasextracted byCauchy method. Combined with genetic algorithm, the diagnosis model of coupling matrixwasconstructed, and the diagnosis programs (Matlabcodes) of the cavity band-pass filterwere developed.The coupling matrixwasextracted from the simulated or testedSparameters of the filter, and then compared with the ideal coupling matrix.The differences between twomatrixesgave thedirection and amplitude of the next tuning of the filter. Taking the development of a7order cavity filter as an example, Matlaband HFSS co-simulationwerecarriedout. After the simulation and optimization process, the return loss meetsthe expected target,and the validity of the method is verified.关键词
