Abstract:
1. An active signal tap device comprising: a signal input; a signal output; a signal tap output; a single directional coupler in series between the signal input and the signal output, the single directional coupler providing a single data signal tap to a combined port of a diplex filter; and an active component coupled to an output of the diplex filter; a first AC power passing choke; a second AC power passing choke connected to the first AC power passing choke; an AC output tap between the first and second AC power passing chokes; an AC to DC power supply connected to the AC output tap; an amplifier connected to the DC power supply; a circuit in parallel to the two AC power pass/tag chokes, said circuit comprising a first capacitor connected to the directional coupler connected to second capacitor, the first diplex port connected to an output of the directional coupler and comprising a first high pass filter and the first low-pass filter; the first attenuator connecting an output of the first high-pass filter to an input to the amplifier; and a second diplex port connected to an output of the amplifier and comprising a second high-pass filter and a second low-pass filter.
