METHOD AND DEVICE FOR JAMMING COMMUNICATION CHANNELS Russian patent published in 2004 - IPC

FIELD: radio engineering; jamming radio communication networks. SUBSTANCE: proposed method designed to generate jamming for users of modern radio communication networks whose numbers are unknown and who use duplex separation of receiver and transmitter tuning frequencies includes reception of all signals in base station radiation band, generation of carrier wave, noise generation at operating frequencies of mobile subscribers by modulating carrier wave by base-station signals, amplification of noise signal, and its radiation. Communication channel jamming device implementing this method has following newly introduced components: input filter, first and second band filters in receiving channel; second microwave amplifier, first and second band filters in transmitting channel. In addition it is provided with newly introduced crystal oscillator, intermediate-frequency amplifier, lowband filter, first and second attenuators. EFFECT: provision for jamming cellular communication system users residing in confined but known region whose numbers are unknown. 2 cl, 5 dwg, 1 tbl
