を特徴とする誘電体共振器制御型発振器。 In an oscillator in which an oscillation element and a dielectric resonator are housed in a metal case and sealed with a metal cover, a metal bellows with one side sealed with a metal plate is attached to the dielectric resonator on an inner surface of the metal cover. At the same time, a laminated piezoelectric actuator is provided inside the metal bellows, and the length of the metal bellows is changed by applying a voltage to the laminated piezoelectric actuator, thereby increasing the facing distance from the dielectric resonator. A dielectric resonator controlled oscillator characterized in that it is configured to be variable.
