Title :
20/spl deg/K-Cooled Parametric Amplifier for 46 GHz with Less Than 60/spl deg/K Noise Temperature
Abstract :
The first 20°K-cooled degenerate parametric amplifier for 46 GHz is described. New 20°K-cooled circulator and Schottky barrier junctions are used. Its noise of less than 60°K means almost an order of magnitude improvement over previous uncooled amplifier.
