Satellite transponder with a system and a method for processing communication data by analog digital conversion of the signals, formation of frequency channels and combination of them by a switch with a plurality of stages.

摘要

An apparatus comprising a backplane and a number of transponder slices connected to the backplane to form a transponder. The number of transponder slices comprise an analog front end configured to receive an analog input comprising a first plurality of bandwidths and a first plurality of interface frequencies, analog to digital converters configured to convert the analog input to digital signals, a digital channelizer configured to process the digital signals to generate a plurality of frequency slices, a digital combiner configured to assemble the plurality of frequency slices to form output sub-bands, a digital switch configured to route the plurality of frequency slices from the digital channelizer to the digital combiner, digital to analog converters configured to convert the output sub-bands to an analog output, and an analog back end configured to transmit the analog output comprising a second plurality of bandwidths and a second plurality of interface frequencies.
