FIELD: radio technology.
SUBSTANCE: invention is related to creation of artificial interference in radio communications. A device for blocking unauthorized transmission of information to control unauthorized devices contains an antenna, a receiver, an amplifier, a noise generator, a signal adder, a bandpass filter, a two-position switch, a control device, a spectrum analyzer, a frequency register, a second control device, a frequency code register, N frequency synthesizers, a second on/off switch, second amplifier. The spectrum analyzer is configured to detect frequencies with a power level greater than the specified one. The codes corresponding to the detected frequencies are loaded into the frequency register. The first control device is configured to send a signal to the frequency register about unloading codes corresponding to the detected frequencies for writing to the frequency code register and to send a signal about loading frequency codes to frequency synthesizers to generate analog signals with suppression frequencies, which are summed by the signal adder. The output signal of the adder is fed to the second input of the second on/off switch, from the output of which the signal is fed through the amplifier and the first on/off switch to the antenna.
EFFECT: increasing the probability of guaranteed radio suppression.
