Abstract:
1. A dielectric resonator oscillator comprising: an MMIC; a transmission line; and a dielectric resonator disposed on a dielectric substrate, wherein the MMIC comprises wherein an active element on the MMIC is connected to the transmission line with metallic wires or metallic ribbons, wherein the dielectric resonator is electromagnetically coupled to the transmission line, wherein the dielectric resonator oscillator further comprises a member for oscillating frequency regulation formed on the dielectric substrate, wherein the member for oscillating frequency regulation comprises an open stub formed in the middle of the transmission line on the dielectric substrate on a side near to the active element when viewed from the dielectric resonator, wherein an oscillating frequency of the dielectric resonator oscillator is regulated by a length of the open stub, and wherein the open stub disposed in the transmission line on the dielectric substrate is formed opposite the dielectric resonator with the transmission line interposed therebetween.
