PULSE SIGNAL AMPLIFIER Russian patent published in 2011 - IPC H03K5/02 H03F3/66 

FIELD: physics.

SUBSTANCE: proposed amplifier comprises first mixer (C) (1), sine oscillation generator (3), first modulating oscillation generator (5) and amplifier (10). Additionally, amplifier comprises second C (7), second modulating oscillation generator (9), and output unit (12) made up of adder or multiplier, while frequency of second modulating oscillation is selected to be lower than that of first modulating oscillation. Second modulating oscillation is fed to C (7) and amplifier (10) to ensure phase coincidence of envelope in second signal second modulating frequency at first input (11) of output unit (12) and amplified oscillation at its second input (13). Better result is ensured if amplified pulse is incorporated with half-period of second modulating oscillation. For this relevant frequencies are selected at generators (3, 5, 9).

EFFECT: amplification of pulse signals with a priori unknown characteristics, synchronisation of amplifying oscillations.
