| 664 GHz Sub Harmonic Mixer Based on “T” Anode GaAs SBD Membrane Circuit |
|
|
| Abstract:—664GHz 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 5μm. Parasitic parameters of “T” anode design were analyzed and membrane process was developed to improve high frequency performance. The mixer was characterized in 664GHz receiver setup. Double side band conversion loss of the mixer was 9.9dB at 664GHz room temperature. |
