Abstract:
For use in a multibeam satellite receiving input beam signals and transmitting output beam signals, wherein the input and output beam signals have corresponding channels arranged in a sequence for carrying channel signals, an analog transponder processor comprising:an input microwave switch matrix for power dividing input beam signals into sets of input beam signals;a plurality of channel processors each receiving at least one input beam signal from the input microwave switch matrix, wherein the channel processors filter the input beam signals into channel signals, wherein each of the channel processors includes a first mixer for changing the frequency of the input beam signals to a common frequency prior to filtering the input beam signals into channel signals and a second mixer for changing the frequency of at least one channel signal from the common frequency such that the at least one channel signal corresponds to a different channel in the sequence than the respective channel of the input beam signals; andan output microwave switch matrix for combining the channel signals into output beam signals, wherein each of the channel signals corresponds to a respective channel of the output beam signals with the at least one channel signal of the output beam signals corresponding to the different channel in the sequence than the respective channel of the input beam signals.
