Title: SATELLITE RELAY DEVICE
Abstract:
Implemented is a flexible satellite relay device which is configured such that, when the frequency band of an input multibeam exceeds the input frequency band of a digital channelizer, in an input-side flexible switch matrix, the multibeam is converted into beams within the input frequency band of the digital channelizer by a command from ground equipment, and the beams are inputted to the digital channelizer, and in an output-side flexible switch matrix, signals exchanged by the digital channelizer are synthesized to a continuous band, and input ports and output ports for the digital channelizer can be shared among all the beams.
