Claims

[Scope of utility model registration request]

In a dielectric filter in which a plurality of resonator holes are provided in the longitudinal direction of a dielectric block and a metallized layer is formed on the inner surface of the resonator holes, metal tubes are tightly fitted into the resonator holes located at both ends of the dielectric block. The tip of the core wire of a coaxial pipe cable used for connection to an external circuit is inserted and fixed into the metal pipe while being covered with the intermediate insulation coating of the cable, and the coaxial cable is coupled using the capacity of the coaxial cable. A dielectric filter featuring:
