A passive signal coupler transfers data signals being transmitted over AC power lines from a first AC power distribution system to a second AC power distribution system. Each leg of the passive signal coupler coupled to a phase of the power line voltage includes a series LC circuit, tuned to the data signal carrier frequency. Each leg coupled to the first power system is terminated in a first winding of a transformer. Each leg coupled to the second power system is terminated in a second winding of the transformer. |
