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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for stacking signals in an expanded frequency range","description":"A device for stacking signals in an expanded frequency range includes an upconverter and a multiplexer.
