FIELD: radio engineering, in particular, satellite TV and communication. SUBSTANCE: input of receiver provides separation of input wave with arbitrary polarization into orthogonal polarization constituents, which are amplified by means of low- noise amplifiers and then are added to get initial polarization. Subsequent polarization conversion by means of polarizer uses amplified input signal. EFFECT: decreased influence of active losses in polarizers on noise temperature in input circuits. 1 dwg
