ABSTRACT:
A coupling network has a first power line interface port and a power line modem interface configured to be coupled to a power line modem transceiver. An inductor-capacitor circuit coupled to the power line modem interface has a low-impedance resonant frequency at a signal frequency of the power line modem transceiver. An inductor having a corner frequency between the signal frequency and the power line frequency has a first end and a second end. The first end of the inductor is connected to the inductor-capacitor circuit and a second end of the inductor is coupled to an alternating current ground coupled to the transceiver ground. The inductor couples the first power line interface port to a power supply interface port.
