Abstract: A signal coupling device comprises a low-frequency circuit including a magnetic ring having an opening and a high-frequency circuit including a rod-shaped magnet. A first-level circuit is formed around the magnetic ring and extends between a first-level circuit input and a first-level circuit output. A second-level circuit is formed around the magnetic ring and extends between a second-level circuit input and a second-level circuit output. The high-frequency circuit includes a third-level circuit formed around the rod-shaped magnet and extends between a third-level circuit input and a third-level circuit output. A fourth-level circuit is formed around the rod-shaped magnet and extends between a fourth-level circuit input and a fourth-level circuit output. The first-level circuit output is coupled to the third-level circuit input and the second-level circuit output is coupled to the fourth-level circuit input.

Abstract: Improved balance winding of electronic components including common-mode chokes and methods for using and manufacturing the same. In one embodiment, the common-mode choke includes a core and a pair of windings. The first winding and the second winding are alternatingly wound around the core with each respective winding being flipped at least once over the traverse direction of the winding barrel of the core. In one variant, the number of flips is dependent upon the core geometry, number of windings, and/or the specification limits on electrical balance. In another variant, the windings are first twisted and/or braided prior to being wound onto the winding barrel of the core.
