  • Power passing termination tap
    Patent number: 10897653
    Abstract: A tap has an input, an output, and first and second tap outputs. A first transmission line extends between the input and the output and includes a low-pass filter. A second transmission line extends between the input and a switch, and includes a directional coupler and a first high-pass filter. An AC/DC converter is coupled to the first transmission line to operate the switch between open and closed conditions, in response to existence and absence of power in the first transmission line, respectively. In the open condition of the switch, the second transmission line is coupled to a resistor and a ground. In the closed condition of the switch, the second transmission line is coupled to a second high-pass filter and the output. A splitter is coupled between the directional coupler and the first and second tap outputs.
