FIELD: radio engineering.
SUBSTANCE: invention may be used in duplex radio channels of control and packet radio networks of effective command communication under narrow-band interference effect. Narrow-band interference suppressor includes broadband amplifier of intermediate frequency, protection unit, adder unit 1, matched filter, control unit. In addition, protection unit contains n of parallel channels. Each parallel channel contains intermediate frequency amplifier, narrow band suppressing element, phase inverter, switch, narrow-band filter, and delay line and adder unit 2.
EFFECT: improvement of received signal validity.
