Time delay equalizer for high-temperature superconduction microwave filtering group

This invention refers to analog signal process and communication technology, especially refers to the group delay equalization of high temperature superconductive filter used in high temperature superconductive film technology field, which contains high temperature superconductive microstrip filter, 3db mixing coupler and two single end reflection filter, is a plane microstrip structure and adapts for making phase equalization and reducing phase distortion to the high temperature superconductive filter of RF front end in satellite receiving system and receiving front end in base station of mobile communication system. Said invention is integrated in one medium substrate and has more stable performance.
