Results of noise and impedance optimization of a W-band receiver-module are given. A wideband compact receiver-module for MM wave passive imaging array has been developed on the basis of InP MMIC LNA and a highly sensitive impedance matched low-barrier detector diode. Achieved bandwidth is 85-100 GHz, the gain factor is 30 dB that was sufficient to provide 15 mK/Hz1 temperature sensitivity of the...
The effect of active layer homogeneous doping in a low-barrier metal-semiconductor contact with near-surface delta-doping on current and capacitance characteristics have been investigated. Difference in characteristics of diodes with Mott and Schottky contacts develops with increasing doping, which results in partial active layer depletion. For really important thickness of an active layer in microwave...
