Abstract
A device for stacking signals in an expanded frequency range includes an upconverter and a multiplexer. The upconverter is configured to receive upstream signals that are in a first frequency range, upconvert some of the upstream signals that are in a first frequency sub-range of the first frequency range and pass some of the upstream signals that are in a second frequency sub-range of the first frequency range. The multiplexer is configured to stack the upconverted upstream signals and the upstream signals in the second frequency sub-range and output the stacked upstream signals.
