Abstract

The design and characterization of a Q-band passive single-balanced mixer in 0.15 μm GaN/SiC HEMT process is presented. The proposed mixer architecture with diplex filters operates both as a frequency up-converter and a down-converter. The measured down and up-conversion losses are better than 10.3 dB and 11.2 dB respectively from 32 GHz-50 GHz for a moderate LO power level of 15 dBm. The measured LO-RF port isolation is higher than 38 dB across the frequency band. The input-referred 1dB compression point is at 8.5 dBm for IF=1 GHz at LO power level of 15 dBm.
