FIELD: radio engineering. SUBSTANCE: proposed amplifier is designed for use in pulse-operated radio receivers incorporated in short-range multichannel navigation systems or other multichannel pulse-operated radio systems. Length of short pulses 6 through 9 corresponding to wavefronts of pulse noise of adjacent frequency channels is selected in radio-frequency amplifier circuit 1 through 5 up to narrow-band filter 10 and detector 12 which provides for pulse selectivity in adjacent frequency channels without impairing sensitivity and without suppressing useful signal by heavy noise of adjacent channel. EFFECT: enhanced efficiency of pulse selectivity for adjacent frequency channels in pulse-operated receivers. 7 dwg
