Transmitter/receiver interface apparatus and method for a bi-directional
transmission path
摘要:
A transmitter/receiver interface (12) for use with a bi-directional transmission path (18) couples a transmitter (14) and a receiver (16) to the bi-directional transmission path (18). The transmitter/receiver interface (12) separates transmitted signals (20) and received signals (22) and routes them from the transmitter (14) and to the receiver (16) with negligible interference. The transmitter/receiver interface (12) incorporates coupling elements (44 and 50) that couple the transmitter to the transmission path and incorporates networks that couple the receiver to the transmission path. Impedances of the networks are derived based on the coupling elements and the transfer characteristics of the transmission path to provide consistent attenuation of the transmit signal over a large frequency range.
