Paper Abstract

A cooled HEMT low-noise amplifier has been designed for a submillimeter heterodyne balloon-borne receiver working at an intermediate frequency of 6 GHz. A minimum noise temperature of 16 K has been achieved at a cryogenic temperature of 27 K. Different methods for an accurate noise figure measurement in a cryogenic environment will be discussed.
