Embedded Magnetics Opens Door to New Approach to Circuit Design

摘要

mpedance matching and filtering of wide bandwidth data lines has long been the domain of hand-wound toroidal chokes and transformers. A new planar magnetic technology is paving the way to the manufacture of these devices utilizing established printed circuit fabrication and IC testing techniques. Advanced magnetic technology leverages the latest 3-D printed circuit board (PCB) processes to manufacture wideband planar transformers and common-mode chokes embedded in a substrate. Well-established PCB techniques are used to more efficiently manufacture reliable, consistent structures.
