Title:
DIELECTRIC RESONATOR, DIELECTRIC FILTER, OSCILLATOR, SHARED APPLIANCE AND ELECTRONIC APPLIANCE
Document Type and Number:
Japanese Patent JP3468093
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To adjust the characteristics of a dielectric resonator device, without lowering no-load Q by mounting dielectric chips on a dielectric resonator part or between dielectric resonators adjacent to each other.
SOLUTION: An electrode 1 with non-electrode forming parts 4a, 4b is formed on the upper surface of a dielectric plate 3 consisting of dielectric ceramics. An electrode with the non-electrode forming parts with the same shapes facing opposite each of the non-electrode forming parts 4a, 4b is formed on the lower surface of the dielectric plate 3. Thus, each of the non-electrode forming parts facing opposite each other are actuated as the dielectric resonator parts of a TE 010 mode. The resonance frequency of the dielectric resonators is, for example, in a 20 GHz zone. Each of the dielectric chips 21a, 21b, 21c, 21d, 21e with rectangular parallelepiped shapes are adhered and fixed at a prescribed position of the dielectric plate 3 by using, for example, an epoxy adhesive. Thus, the characteristics of the dielectric resonator device are adjusted by providing the dielectric chips 21a to 21e on the dielectric plate 3.
