HECTOMETER RF DATA TRANSMISSION DEVICE WITH HYBRID COMBINER

摘要

FIELD: radio communications.;SUBSTANCE: invention relates to radio communications and can be used for receiving and transmitting information in radio communication systems of the hectometer radio frequency (HRF) range at stationary objects of railway infrastructure and mobile objects of railway transport. The proposed device solves the technical problem of ensuring the simultaneous operation of two transceivers per antenna in the HRF range with a frequency separation of at least the channel width, namely 10-20 kHz (0.5-1.0 % of the carrier frequency of the useful signal). The device for transmitting data of the hectometer radio frequency range contains a built-in controller for receiving and transmitting data containing an interface for connecting external devices, a digital data processing device that includes an interface for connecting an external data source, an interface for connecting an external controller for receiving and transmitting data. The device also contains a data transmission path, a data receiving path, a high-speed switch for switching channels for receiving and transmitting data, a voice data transmission path, a voice data receiving path, an adder, an antenna-matching device, a built-in GPS/GLONASS navigation satellite system signal receiver.;EFFECT: ensuring the simultaneous and independent operation of a radio modem for data transmission with a transceiver of the HRF range radio station on stationary and mobile objects.;1 cl, 2 dwg
