ABSTRACT: This demonstration features the Maury Microwave MT7553A03 noise receiver module in a cryogenic noise parameter system. This system is the industry’s first commercial tool to extract noise parameters down to 4 Kelvin at cryogenic temperatures while utilizing a cryogenic solid-state tuner to achieve non-50 ohm environments at the DUT input. These noise parameter measurements are an essential tool to optimize LNA for minimum low noise figure at these temperatures.
