Anyone who works in the electrical and electronics industries understands one fact about moving current through conductors: everything is a resistor, and everything is an inductor. That’s especially true for AC flow, and even more so at high frequencies, were both skin effect and proximity effect must be considered in circuit design. For cables, conductors with multiple strands are the solution to skin effect, but proximity effect requires a balance between conductors that are surrounded by others, and those that operate on the outer surface of the cable.

The answer to that question is Litz wire, a traditional radio frequency solution that goes back to the early days of radio but is more relevant than ever for a host of high-frequency devices. 

Jim Anderton spoke with Joshua Spaulding, Design Engineering Manager with New England Wire Technologies about the challenge of RF cabling, and how Litz wire solves high frequency issues in many devices.
