A 100GHz Schottky diode mixer based on quartz substrate is presented, which will be used as the detector for the millimeter imaging. The Schottky diode is modeled based on its physical dimension thus its high frequency parasitic parameters can be fully taken into consideration. The measured conversion loss is better than 10dBm over 95~105GHz with 8dBm LO pump at 49.53GHz. The measured result is also in excellent accord with the simulated model.
