Radio Transmitter with Frequency Modulation and Time Division of Channels for High-Information Telemetry Systems

The paper studies а communication device that is applied in radio telemetry systems for information transfer with frequency modulation and time division of channels. The method for forming a data flow with the doubled informational content (2×640 kHz) in the telemetry system structure of the “SKUT-40” type is considered in the article. The employed circuit engineering solutions make it possible to reduce the effect of crosstalks at the borders of forming measured and service signals upon the nominal value of the reference frequency. The created data flows are transmitted over a radio channel through the modified standard radio transmitter of the UPM type and received by receiving and recording equipment like “Vector” at two carrier frequencies. The result of the proposed technical solutions is the essential increase (by 2 times) of information content of the radio channel of the “SKUT40” type that is a contributing factor for rather promising practical implementation of the reached technical baseinto the existing complexes of telemetry measurements.
