Abstract

Disclosed is a radio frequency communication and jamming device configured for physically secured friendly radio frequency communication and for jamming hostile radio frequency communication, the radio frequency communication and jamming device including: an antenna arrangement having a transmission section for transmitting outgoing signals and a receiving section for receiving incoming signals; a receiver device configured for extracting an incoming information signal from the incoming signals received via the receiving section of the antenna arrangement in a receiving frequency band; a jamming generator configured for generating at least one jamming signal for jamming at least one jamming frequency band, wherein the jamming signal is transmitted as one of the outgoing signals via the transmission section, wherein the at least one jamming frequency band includes the receiving frequency band; and a self-interference cancellation device configured for cancelling portions of the at least one jamming signal in the incoming signals received via the receiving section at least in the receiving frequency band.
