Abstract
System and method that permits fully automated production of RF hybrid devices or chokes comprised of electrical wires and a main body made of ferrite toroids are disclosed. RF chokes produced according to current invention may be used as directional couplers, in-phase splitters, balanced/unbalanced (BALUN) matching devices, radio frequency (RF) transformers etc., and may achieve high repeatability and improved electrical performance without adversely affecting electrical characteristics of the RF hybrid devices.
Claims16
An apparatus comprising:
- a main body made of a magnetically permeable material, having at least one cavity through it;
- and
- a multi-wire flat cable having at least two wires held on a flat insulation material, wherein the ends of said wires are connected to each other according to a desired scheme after said flat wire has been inserted through said at least one cavity.
A RF choke production method comprising:
- cutting a flat multi-wire cable at a desired length;
- inserting said flat multi-wire cable through one or more cavities of a main body made of magnetically permeable material so that the two ends of said flat multi-wire cable are close to each other;
- connecting by conductive material loose ends of wires in said multi-wire cable to each-other to form a continuous conductor having a required number of turns encircling said main body through its cavity.
