US 10,897,653 B2 · Power passing termination tap

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.

Dependent claims

A tap comprising:

an input, an output, and first and second tap outputs;
a first transmission line extending between the input and the output, the first transmission line including a low-pass filter for removing high frequencies from a first signal in the first transmission line;
and
a second transmission line extending between the input and a splitter coupled to the first and second tap outputs, the splitter simultaneously coupling the input to the first and second tap outputs in electrical contact and communication, and the second transmission line including only a high-pass filter for removing low frequencies from a second signal in the second transmission line, wherein the high-pass filter is upstream from the splitter.
