Patent ID: 6990682

Claim:
A two-way CATV system comprising: at least one bidirectional amplifier provided on a CATV transmission path for connecting a CATV center station to a subscriber home; bias voltage superposing means for superposing, with an AC frequency bias voltage within a bidirectional amplifier at the terminal of said at least one bidirectional amplifier, a downstream RF frequency signal transmitted along a coaxial transmission path subordinate to the bidirectional amplifier at the terminal; and bias current adjusting load means, provided at the end of said coaxial transmission path, for setting an AC frequency bias current corresponding to an application of the AC frequency bias voltage superposed by said bias voltage superposing means and for flowing a uniform AC frequency current on said coaxial transmission path; and wherein said bias current adjusting load means includes an inductive element in series with a resistance element coupled by a parallel connection to a terminating resistance element, wherein said inductive element is selected so that the resistance of the coupled current adjusting load means and terminating resistance element approximates the resistance of the terminating resistance element for RF signals.
