Abstract

A power line communication device comprises a plurality of transformers in series. These transformers are used to increase the voltage of a digitally encoded signal in a stepwise fashion prior to being coupled into a power line. While a transmit path includes at least a first transformer and a second transformer in series, a receive path may include only one of these two transformers. For example a receive path may include only the first transformer, or include the first transformer and a third transformer. The net ratio of voltage increase and decrease may be different in the transmit and receive paths.
