Abstract From the Canadian patent

A radio frequency (RF) router is disclosed. The RF router utilizes resistive input signal splitters on an input module to divide input RF signals received at RF signal input terminals into a plurality of backplane signals. The backplane signals are transmitted to one or more output modules where the backplane signals are each resistively split into a plurality of split backplane signals. A split backplane signal corresponding to each of the input RF signal is coupled to a backplane signal selection stage. The backplane signal selection stage couples on of the split backplane signals to an RF signal output terminal.

  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
