Abstract


In microwave filters , manufacturing errors is an important factor affecting their electrical properties . However, for a long time , works neither establish the relationship between the filter manufacturing error and its electrical properties , manufacturing error and technical parameters of the relationship is not yet in-depth analysis , resulting in a the filter long development cycle , high cost problems . To this end , this paper studies the impact of manufacturing factors on the electrical properties of the cavity filter . First, for the filter different processing methods turning conductor and milling after the model of the body wall of the rear cavity ; Secondly, the study of a simulation method of a manufacturing error - containing cavity filter , the filter model containing the error introduced into the electromagnetic field simulation software simulation of the electrical properties of manufacturing error filter ; Finally, the S-curve obtained from the simulation data extracted coupling matrix and establish regression analysis model coupling matrix under different processing parameters obtained by simulation , in order to establish the relationship between the process parameters and filter the electrical properties , and provide a basis for the choice of filter processing parameters .
