FIELD: communication.SUBSTANCE: invention relates to means of communication and specifically to means of radio communication unit of ultrashort wave range. Said technical result is achieved by the fact that in the microwave radio station, comprising transceiver, remote control panel and antenna, additionally, terminal equipment (TE) telephone and telegraphic communication, equipment adaptation, unit of digital seal and unit of separation filters, a transceiver is composed of unified units, consisting of control and switching unit (TC), control panel, micro computer. Basic receiver-exciter including low frequency amplifier (LF), unified frequency synthesizer (FS), a reference generator, high-frequency switch, communication device, receiver and a buffer amplifier, matching unit transceiver, controlled generator, the power amplifier, switch of transmitting radio station, filter additional selection and automatic matching device, as well as by the fact that SR radio station unit comprises a unit of connection circuits, low frequency amplifier (LF), regenerator, switch, switch, register unit, information output device, receiver of tonal call (PTV), level coordinator, communication device, meter of intermediate frequency (IFF), generator of time markers (TM) and memory unit, receiver includes first, second, third and fourth high frequency amplifiers (HF), unit of automatic adjustment of circuits (AAC), switch subranges, first mixer, delay line. Pulse noise suppressor, quartz filter, splitter, a first intermediate frequency (PCh1), second mixer, quartz generator and limiter-discriminator.EFFECT: technical result of the declared invention is expansion of functional capabilities of the radio station, particularly organisation simplex and duplex radio channels in a wide frequency range of metric waves, transmitting the telephone and telegraphic messages and data with high reliability of transmitting information.3 cl, 3 dwg |
