CROSS REPEATER FOR ORGANISATION OF INTERACTION OF RADIO NETWORKS OF SINGLE-FREQUENCY AND TWO-FREQUENCY SIMPLEX OPERATING IN TWO DIFFERENT FREQUENCY RANGES, AND CONFERENCE COMMUNICATION RADIO NETWORK

摘要

FIELD: radio engineering, communication.SUBSTANCE: in the cross-repeater the interaction of radio networks of a single-frequency and two-frequency simplex operating in two different frequency ranges, and a conference communication radio network is implemented. The cross-repeater contains two pairs of simplex radio stations connected to the power unit and to each other through an interface which in each pair through the duplex filter are connected to common antenna and operated at unmatched frequencies of conditional range. Interface has multiport adders - two per radio station, the low-frequency output of the receiver of each of which is connected to the noise suppressor and through the respective adders with the input of submodulator of transmitter of the radio stations operating in one of frequency ranges, and the output of the noise suppressor of each of radio stations through the respective adders is connected to the control transmitter of radio stations operating in another frequency range. Pairs of simplex radio stations can operate in the ranges respectively 160 MHz and 460 MHz.EFFECT: expansion of scope of application of repeaters for organising of interaction of several radio networks operating in different frequency ranges.2 cl, 3 dwg
