Abstract
We have realized receiving - amplifying circuits for a frequency range of 21.0-23.0 GHz using frequency conversion down to 1.5 GHz is put. Mixers and ultra low noise transistor amplifiers based on HEMT - transistors cooled down to low temperatures were used. The cryoelectronic ultra low noise transistor amplifier realized (amplification factor K_a = 50 dB and own noise temperature T_n = 45 K) could be used in systems of satellite and space communication, and also for the realization of spectrometric systems.
