(English Abstract) |
A push-push voltage controlled dielectric resonator oscillator(VCDRO) with a modified frequency tuning structure using broadside couplers is investigated. The push-push VCDRO designed at 16GHz is manufactured using a low temperature co-fired ceramic(LTCC) technology to reduce the circuit size. The frequency tuning structure using a broadside coupler is embedded in a layer of the A6 substrate by using the LTCC process. Experimental results show that the fundamental and third harmonics are suppressed above 15dBc and 30dBc, respectively, and the phase noise of push-push VCDRO is -97.5dBc/Hz at an offset frequency of 100 kHz from the carrier. The proposed frequency tuning structure has a tuning range of 4.46MHz over a control voltage of 1–11V. This push-push VCDRO has a miniature size of 15 mm×15 mm. The proposed design and fabrication techniques for a push-push oscillator seem to be applicable in many space and commercial VCDRO products.
