Abstract :
A dielectric resonator balanced second harmonic quasi-optical self oscillating mixer is demonstrated for the first time. Dielectric resonator coupled HEMT devices were used to generate the signal for the second harmonic mixing. A patch antenna and directional couplers were used to feed the RF. The circuit exhibits a conversion loss of 22 dB from 59.4 to 60.4 GHz, radiation leakage of -34 dBm at 60 GHz, and IF phase noise of -68 dBc/Hz at 10 kHz offset.
