Abstract

PURPOSE:To obtain the transformer suitable for the high frequency of 200MHz or more by a method wherein a magnetic core material is wound around with an electric wire covered with silk, cotton, paper, etc. CONSTITUTION:A magnetic core material 100 is wound around with an electrically conductive wire material like copper wire, etc., (electric wire) 511, 521, 531, 541 being covered with one or two kinds of silk, cotton, paper to constitute a high frequency transformer. The magnetic core material is ordinarily a ferrite core, and the high frequency trnasformer is used as an impedance transformer or a pulse transformer in the frequency band of FM, TV. By this way, the insertion loss at the frequency of 200MHz or more can be reduced to obtain a suitable transformer.
