Abstract

PURPOSE:To improve characteristics remarkably by composing a coupler of a group of the 1st and 2nd strands and the 3rd strand wound around core being twisted whose number of twisting times is less than that of the 1st and 2nd ones by a fixed number. CONSTITUTION:This coupler uses troidal core 12 using magnetic material as a raw material, the 1st strand 13 wound around core 12 fixed times, and the 2nd strand 14 wound around core 12 as many times as the 1st strand 13 being twisted fixed times. In addition, the 3rd strand 15 is wound around core 12 being twisted several times less than the number of the 1st and 2nd ones by a fixed ratio, thereby making it possible to improve characteristics remarkably.
