摘要：
In this paper three methods are employed to characterize the equivalent input noise temperature of a cryogenically-cooled IF HEMT LNA. They are the conventional Y-factor method, variable-temperature method and shot-noise method. Through the measurements, their merits and drawbacks are compared.
