Abstract

The invention relates to an equivalent circuit parameter generation method, a multiplexer de-loading method and a multiplexer de-loading device. The equivalent circuit parameter generation method comprises the steps of performing de-phasing loading processing on an original scattering parameter of a to-be-debugged filter in a to-be-debugged multiplexer to obtain a target scattering parameter; converting the target scattering parameter to obtain a corresponding original admittance parameter; subjecting the original admittance parameter to unloading processing of a loading parameter of a common cavity to obtain a target admittance parameter; extracting a pole in the target admittance parameter and a residue corresponding to the pole; and generating equivalent circuit parameters according to the pole and the residue corresponding to the pole. By adopting the method, the multiplexer can be debugged by using a low-cost network analyzer, so that the debugging cost of the multiplexer can be greatly reduced.

Description

technical field [0001] The present application relates to the technical field of microwave device testing, in particular to a method, device, computer equipment and storage medium for generating equivalent circuit parameters, and a multiplexer unloading method, device, computer equipment and storage medium. Background technique [0002] With the deployment of 5G (5th generation mobile / wireless / cellular system, the fifth generation mobile communication system), the wireless communication frequency band has added multiple 5G frequency bands on the basis of the original 2G / 3G / 4G frequency bands. Since the frequency bands of 2G / 3G / 4G base stations have already occupied the golden position, the space resources reserved for 5G base stations are relatively tight. In order to solve the above problems, multiplexers can be used to connect systems in different frequency bands together. The multiplexer is composed of multiple different frequency filters, which can generate sufficient o...
