Abstract:
An RF choke comprising:an elongated core having respective first and second diameters;a first group of windings defining a first conductor wound around one of said core diameters;a second conductor defined by respective second and third groups of windings wound around the other of said core diameters, each of said second and third groups of windings being wound around said core in a winding direction which is opposite a winding direction of said first group windings;each of said first, second and third groups of windings are connected to each other at respective ends in series, with said second group being disposed between said first and third groups of windings;a plurality of resistors connected to said first and second conductor; anda space (S) located between the last turn of the first conductor and the first turn of the second conductor such that the flux generated in the windings is effectively canceled.
