Abstract

A dielectric resonator oscillator utilizing transmission-type injection-locking for frequency stabilization is disclosed as including a transistor, two microstrip lines, and a dielectric resonator. One microstrip line is coupled to the transistor, while the other microstrip line receives the broadband signal. The dielectric resonator is positioned adjacent to and between the first and second microstrip lines and is operable for coupling an injection-locking signal into the transistor for locking the oscillation frequency of the oscillator. The two microstrip lines are preferably oriented at right angles so that various sizes of the dielectric resonator can be accommodated.
