Method and device for providing broadband over power line communications
First Claim
1. A device for communicating broadband data signals over a power line, comprising:
- a port configured to be coupled to the power line;
a node coupled to said port;
a transmit portion and a receive portion coupled to each other at said node;
each of said transmit portion and said receiver portion comprisinga delay circuit coupled to said node and configured to delay the data signals, anda switch coupled to said delay circuit, said switch having an open configuration and a closed configuration; and
wherein the broadband data signals are communicated in a frequency band and wherein each said delay circuit is configured to delay data signals substantially the same amount across substantially the entire frequency band.

Abstract
A transmit and receive circuit for use in power line communication devices is provided. One embodiment of the circuit includes a receive channel with a first delay circuit coupled to a first switch having an open configuration and a closed configuration a first switch. The circuit also may include a transmit channel coupled to the receive channel at a node and including a second delay circuit coupled to a second switch having an open configuration and a closed configuration. When the switch of either channel is closed, the switch of the other channel is open. Data signals traversing either channel when that channel'"'"'s switch is closed, are phase shifted approximately three hundred and sixty degrees and conducted back to the node.
