Patent ID: 7054279

Claim:
A method of optimizing signal transformation from a twisted pair transmission line to a combination transmitter and receiver for a frame-based communications network, the transmitter having a transmit output pair port for transmitting signals onto the frame-based communications network over the twisted pair transmission line, the receiver having a receive input pair port for receiving signals from the frame-based communications network over the twisted pair transmission line, the method comprising: coupling a transformer between the twisted pair transmission line and each of the transmit output pair port and the receive input pair port, the transformer having a coil across the twisted pair, a transmit coil across the transmit output pair port, and a receive coil across the receive input pair port, wherein a turns ratio between the transmit coil and the coil across the twisted pair is designated wt:1, wherein a turns ratio between the receive coil and the coil across the twisted pair is designated wr:1, and wherein wr>wt.
