Abstract:

664 GHz sub harmonic mixer for ice cloud detection was designed and fabricated， based on 0.5 μm “T” anode GaAs SBD membrane integrated process with thickness of 5 μm. Parasitic parameters of “T” anode design were analyzed and membrane process was developed to improve high frequency performance. The mixer was characterized in 664 GHz receiver setup. Double side band conversion loss of the mixer was 9.9 dB at 664 GHz room temperature.
