RECONFIGURABLE SATELLITE PAYLOAD FOR ANALOG PROCESSING OF RADIOFREQUENCY SIGNALS

Exemplary embodiments are directed to a reconfigurable system for the analogue processing of radio frequency signals in a satellite communications system. The system receives a pre-selected first intermediate frequency and selects one or more first frequency channels from the input signal, to amplify and provide automatic gain control of the selected first channel signals and to translate the selected first channels to one or more second frequency channel signals within a pre-selected second intermediate frequency band. The first and second intermediate frequencies are selected to minimize conversion of the uplink and downlink signals. The system provides a generic flexible communications satellite payload architecture based on single channel agile conversion and provides adjustable frequency conversion and bandwidth to individual satellite channels, allowing in-orbit flexible reconfiguration of payload frequency plan and operation.
