FIELD: electricity.SUBSTANCE: invention is related to electric engineering and may be used in frequency filters for wireless devices for various applications, for example, in harmonic filters of powerful high-frequency radio transmitters. A winding contains N wires connected in parallel and mounted on a circular frame. Each wire is placed partially to the inwards protruding part of the frame with holes for wires, which are placed in a circumferential direction of the protruding parts with gaps in-between the holes. Each wire is placed partially in the holes spaced from each other at a distance of the total gap between them, including at least N-1 diameters of the holes and N gaps between the adjacent holes. Wires of the winding may have a current-conductive coating, for example, a silver one.EFFECT: improvement of Q-factor.2 cl, 1 dwg |
