Abstract

An arrangement for coupling data between a power line (300) and a communication device (325) includes an inductive coupler (305) that employs a power line conductor as a primary winding, a capacitor (310) connected across a secondary winding of the inductive coupler (305) for creating a resonant circuit with the secondary winding at a frequency within a desired frequency band, and an impedance matching transformer (315) for connecting a communications device (325) to the secondary winding. The resonant circuit has a loaded Q consistent with the desired bandwidth. An alternative arrangement includes a capacitor (410) in series with conductive cylinder section (505) and (510) between the power line and communication device (435), where the capacitor is for blocking power line voltage while passing a signal between the power line and the communication device, and the conductive cylinder sections (505) and (510) appears as a low inductance to the signal.
