Abstract
Ultra-low-noise amplifiers, having noise temperature 10-20 K under moderate (uncryogenic) cooling, for the ranges 0.5-1, 1-2, 2-4 GHz are presented. The design peculiarities aimed to the most effective realization of modern PHEMTs potential are described. Relying on obtained experimental data prediction, it is drown that noise temperature of uncooled broadband amplifiers may be reduced down to 10 K over 0.3 to 3 GHz band.
