LOW-NOISE MICROWAVE AMPLIFIER Russian patent published in 1998 - IPC

Abstract RU 2108658 C1

FIELD: electric communications; microwave radio receivers. SUBSTANCE: amplifier uses variable redundancy circuit arrangement and can operate in quasi-redundant mode at uniform expenditure of amplifier life. Amplifier has three amplifiers 1,2,3, adjustable amplifier 4, two matched loads 5,6, three switching units 7,8,9, addition bridge 10, three switches 11,12, 13, control unit 14, and detector 15. Series circuit is used instead of balanced one. EFFECT: reduced noise of ratio receiving channel, improved reliability of amplifier which remains serviceable in case of failure of one or even two amplifiers. 4 cl, 6 dwg
