LOW-NOISE UHF AMPLIFIER Russian patent published in 2005 - IPC

Abstract RU 2253941 C1

FIELD: radio communications.

SUBSTANCE: device has amplifiers 1-3, adjustable amplifier 4, synchronized loads 5, 6, commutation blocks 7-9, adder bridge 10, keys 11-13, control block 14, detector 15, multi-channel power block 16. due to insertion of multi-channel power block 16 reliability of amplifier operation increases due to individual power settings for amplifier, to prevent breakdowns of amplifier transistors because of occurrences of pulse current in case of short circuits in amplifying elements and control of their state is also provided.

EFFECT: higher reliability.
