Abstract

The utility model discloses a novel high-time-delay balance coupling filter. The filter comprises a housing and a cover plate, wherein an input port and an output port are arranged outside the housing, and a groove is opened in the housing. The groove is dug deeply to form five independent cavities as resonant cavities, wherein a resonant rod is arranged in each resonant cavity, a second resonant rod is respectively coupled with a first resonant rod and a third resonant rod, and a fourth resonant rod is respectively coupled with the first resonant rod, the third resonant rod and a fifth resonant rod. The cover plate covers an opening position of the housing; screw holes corresponding to positions of resonant holes are opened in the cover plate, and the cover plate is connected with each resonant rod via screws, and another cavity is dug between a first resonant cavity and a fourth resonant cavity, wherein a resonant rod is arranged in the resonant cavity, and the resonant rod is respectively coupled with the first resonant rod and the fourth resonant rod. The filter of the utility model has the advantages of being simple in structure and convenient for assembling, improving high-time-delay fluctuation and three-stage intermodulation indexes based on original technology, enhancing the coupling amount, minimizing production procedures, improving reliability and reducing the cost.
