Abstract

A circuit arrangement for combining signals in a cable set-top box or television receiver. An out-of-band upstream amplifier and a cable modem upstream amplifier have their outputs combined at a combiner before being passed to the cable through a diplexer. The output of the diplexer provides incoming signals for an in-band tuner, a cable modem tuner and an out-of-band tuner that can be passed through a low noise amplifier before passing through a three-way splitter to divide the signals to each of the tuners.
