Claims

[Scope of utility model registration request]

In a filter in which a plurality of through holes with a center conductor are provided in a dielectric block and a peripheral conductor is metallized on the peripheral surface leaving one surface with the holes open to form a plurality of resonators, the dielectric block A stator electrode connected to the outer circumferential conductor is provided on the unmetalized end surface of the dielectric plate, a semicircular rotor electrode is provided on one side of a dielectric plate with a through hole in the center, and a rotor electrode is provided on the periphery of the through hole on the other side. A rotor provided with a rotor center electrode connected to an electrode is fixed to a rotating shaft provided through the center conductor with the rotor center electrode in contact with the center conductor of the resonator, and the rotating shaft is rotated. A high-frequency filter whose center frequency can be changed by changing the center frequency of the filter.
