ABSTRACT:
Radio frequency chokes for use in combining and separating radio frequency signals and single phase AC power in the equipment used in cable transmission and distribution systems. The radio frequency chokes include a conductor wound on a magnetic core to form a primary winding upon which first and second swamping circuits are mounted. Each of the swamping circuits include a secondary winding with a resistor connected across the ends thereof with the swamping circuits effectively dampening parasitic resonances in the primary winding which occur in the frequeny range of from about 5 MHz to at least 800 MHz.
