CATV Splitter/Tap

CATV splitter, tap (coupler) are circuits that sample RF transmissions by combining (coupling) signals asymmetrically. The power passing from the input to the output is combined with the coupled output, but the coupled output is isolated from the main output. Any reflected power from the main line output is coupled to the termination. For the isolation to be achieved, coupled outputs must be obtained through well-matched termination at each port. They are commonly used in HFC distribution network.
