Abstract

PURPOSE:To improve the modulation characteristic and a tunable characteristic by forming a part of a case and a cover with a main dielectric resonator and a sub dielectric resonator contained therein inward to a degree not disturbing the electromagnetic field coupling. CONSTITUTION:The main dielectric resonator 1 and the sub dielectric resonator 2 subjected to electromagnetic field coupling with the resonator 1 are contained in the case 5 and the cover 4. The cover 4 and the case 5 are formed inward to a degree not disturbing the electromagnetic field coupling and approach the resonators 1, 2, then the volume of the case is reduced remarkably. Thus, it is possible to set the basic mode of the case 5 to a for higher frequency than the oscillated frequency. Then the modulation characteristic and the tunable characteristic are improved.
