FIELD: radio engineering, communication.
SUBSTANCE: invention relates to satellite telecommunications. A superhigh frequency channel multiplexing device contains multiple elementary filters, connected in parallel to the common output via a transverse waveguide. The lower end of each filter is fixed to the base, common for all the filters. The upper end of each filter lies opposite to the base. Each filter also contains an outer side wall, at least one intracavity, defining an internal channel, a signal input, connected to the intracavity, and a signal output, connected to the transverse waveguide. The multiplexing device also contains a conducting radiating device, which is thermally and mechanically connected to at least two filters. The said conducting radiating device also contains at least one thermal plane and is connected to the outer side walls of at least two filters. The plane is fixed at a level of the filters upper ends.
EFFECT: decrease of the heat transfer rate at the channel section surface, operating in an out-of-band mode.
