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 (G) (3), first modulating oscillation generator G (5) and amplifier (10) with its output making proposed device output. Generator output (3) is connected with output C (1) with its second input connected to output G (5), while first modulating oscillation frequency is selected to me lower than that of sine oscillation. Additionally, device incorporates second C (7) and G (9) of second modulating oscillation. Note here that output C (1) is connected with first input (6) of C (7) with its second input (8) connected with output G (9), while output C (7) is connected to input of amplifier (10) making signal amplifier on second modulating oscillation frequency with bandwidth to allow transmission of said sine oscillation and first modulating oscillation. Note also that second modulating oscillation frequency is selected to be lower than that of first modulating oscillation.

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