FIELD: radio engineering, communication.
SUBSTANCE: creation of a broadband radiocommunication system with a frequency duplex (with increased noise immunity) and with a reduced negative effect of the transmission path of the system on the receiving path of the system by suppressing the combinational frequencies of the transmission path, as well as with a reduced negative effect of the transmission path of the system on the receiving paths of other radiocommunication systems being in close proximity (in order to improve the electromagnetic compatibility), by including electronic tunable bandpass filter (ETBF) 306 in the composition of a transmitter-receiver 302.
EFFECT: improving the quality of communication.
