Abstract
A novel K-band harmonic dielectric resonator oscillator (DRO) is presented. Two identical parallel feedback DROs constitute a symmetric structure by sharing the same dielectric resonator (DR). As a result of this special structure, the odd frequency output components offset while the even harmonic frequency components superimposed at the output port. Odd and even mode analysis method is used in theoretical analysis. As the experimental results shown, the fundamental frequency is 9.45 GHz and the output power at the second harmonic frequency of 18.9 GHz is 9.45 dBm. The suppression of fundamental frequency is about 15.5 dBc. A phase noise of -97 dBc/Hz@100 KHz and -78 dBc/Hz@10 KHz is achieved at the output frequency.
