FIELD: radio engineering.
SUBSTANCE: radio transmitting device includes output power amplifier, parameter control unit, signal control unit, amplitude modulator, two frequency synthesizers, frequency selection switch and two controlled attenuators.
EFFECT: improving interference immunity of communication channel owing to increasing the suppression of parasitic stray radiation of the neighbouring transmitter channel.
