A push–push voltage‐controlled dielectric resonator oscillator (VCDRO) with a modified frequency tuning structure is investigated. The push–push VCDRO designed at 16 GHz is manufactured using a low temperature cofired ceramic (LTCC) technology to reduce the circuit size. The frequency tuning structure is embedded in a layer of A6 substrate by an advantage of LTCC process. Experimental results show that the fundamental frequency suppression is above 30 dBc, and a phase noise of push–push VCDRO presents a good performance of −103 dBc/Hz at 100 kHz offset frequency from carrier. © 2007 Wiley Periodicals, Inc.
