PURPOSE:To compensate the attenuation characteristics of an input-side cable by cinstituting a series arm element by adding natural ferrite materials to an input- side and an output-side center conductor respectively, and by increasing the resistance values of the center conductors according to an increase in frequency. CONSTITUTION:A center conductor 1 is made of an enameled copper wire, etc., and a series arm element 7 is added to the conductor 1. A ferrite core 8 has two through holes 9 and 10, into which an input-side center conductor 11 and an output-side center conductor 12 constituting the conductor 1 are inserted respectively. Those conductors 11 and 12 are connected together in series at a connection part 13. For this core 8, a material having the properity that the resistance value increases with frequency is used as the center conductors inserted into the through holes 9 and 10. |
