Enhancing Heterodyne System Performances Using Fundamental Millimeter Wave Mixers with 36 GHz Instantaneous IF Bandwidth and 35 % Relative Detection Bandwidth

The development of low noise and wide instantaneous IF and RF bandwidth fundamental mixers is reported. The proposed architecture offers attractive potential for ultra-large bandwidth and fast data rates wireless links. Moreover, it could be used to either reduce total power radiometer sensitivity or to enhance large scale mapping heterodyne systems for atmospheric science instruments.
