Communication system for transmission of broadband and baseband information.

摘要

Communications system for transmitting baseband and broadband signals simultaneously, which is ideally suited for interconnecting different types of data terminal equipment (DTE) within a building or limited geographical area. The system includes a backbone communications network (10) formed from a plurality of independent communications systems, being each dedicated to transmit either the baseband signals or the broadband signals. A Filter Coupler network combining and separating the two different type of signals at the distribution level includes a filter network coupled in tandem with a high frequency transformer. In an alternate embodiment the coupler includes a balun transformer coupled to a directional transformer.
