FIELD: radio communications; miscellaneous radiograph and radiophone transmitting equipment.
SUBSTANCE: proposed exciter has series-interconnected pulse shaper, digital modulator, and amplifier-computer unit with synthesizer outputs connected to its inputs, as well as series-interconnected modulator unit and filter unit. Use is also made of input linear envelope AGC amplifier, digital radiated-spectrum limiting unit, synchronizing unit, programming unit, selector, two peak detectors, comparison unit, and series-interconnected automatic channel cutoff stage responding to input signal arrival, peak-voltage control stage, and output amplifier. Connected to synthesizer input is output of control unit whose second output is connected to program unit input.
EFFECT: reduced spurious emission which ensures electromagnetic compatibility with other radio facilities.
