Abstract
A communication device for use on high voltage power lines provides for broadband communications over such high voltage power lines. The device has an impedance matching circuit configured to connect at one end to a high voltage line arrester of the high voltage power line, as well as a limiter circuit coupled to the other end of the impedance matching circuit to limit a voltage associated with a broadband signal. A noise blanker circuit is coupled at one end to this other end of the impedance matching circuit and is configured to inhibit presentation of a time delayed incoming signal to the broadband modem upon detection of electrical noise. The communication device can further comprise link aggregation and/or a differential circuit for providing non-inverted and inverted broadband signals for both reception and transmission. A corresponding method of communicating broadband information over a high voltage power line is disclosed.
