FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used in radiotelemetric systems for obtaining information from mobile objects. Radio transmitting device includes output power amplifier, parameter control unit, control unit signal frequency switch, the first frequency synthesizer, second frequency synthesizer, an amplitude modulator, the first controlled attenuator, the second controlled attenuator, the first controlled frequency divider, the second controlled frequency divider.
EFFECT: technical result is increased suppression of parasitic stray radiation of the neighbouring transmitter channel.
