Signal repeater and method for matching an output impedance of the signal repeater, which amplifies a signal on an electrical line of an electrical grid, to an impedance of a load
First Claim
1. A signal repeater comprising:
- a port configured to connect to an electrical line of an electrical grid between a plurality of devices, wherein communication over the electrical line and between the plurality of devices includes transmission of a first signal, and wherein the port is configured to receive the first signal from the electrical line;
an amplifier configured to (i) receive a second signal based on the first signal, and (ii) amplify the second signal,wherein the port is configured to (i) receive the amplified second signal, and (ii) provide the amplified second signal to the electrical line; and
an adaptive device configured to, based on the first signal, adjust an output impedance of the signal repeater to match a first impedance of a load on the signal repeater, wherein the first impedance is seen by the signal repeater at the port, and wherein the first impedance includes an impedance of the electrical line.

Abstract
A signal repeater includes a port, an amplifier, and an adaptive device. The port is configured to connect to an electrical line of an electrical grid between devices. Communication over the electrical line and between the devices includes transmission of a first signal. The port is configured to receive the first signal from the electrical line. An amplifier is configured to receive a second signal based on the first signal, and amplify the second signal. The port is configured to receive the amplified second signal, and provide the amplified second signal to the electrical line. An adaptive device is configured to, based on the first signal, adjust an output impedance of the signal repeater to match a first impedance of a load on the signal repeater. The first impedance is seen by the signal repeater at the port, and wherein the first impedance includes an impedance of the electrical line.
