ABSTRACT:
A radio frequency choke for use in a cable television transmission and distribution circuit is disclosed. The radio frequency choke comprises a core of zinc-ferrite material as provided by MMG/NEOSID, Ltd., part number 31P0250012, and a wire coil wound around the core. The coil includes a first lead, a first clockwise winding of N1 turns around the core, the first lead being connected to an input of the first winding, a second counterclockwise winding of N2 turns around the core, a third counterclockwise winding of N3 turns around the core, and a second lead connected to an output of the fourth winding. In a preferred embodiment, there are six turns in the first clockwise winding, five turns in the second clockwise winding, and five turns in the third counterclockwise winding. Moreover, in the preferred embodiment, resonance damping resistors of approximately 2 K.OMEGA. are connected between the windings of the radio frequency choke.
