Ultra-wideband balun using a multiaperture ferromagnetic core

Abstract

This paper will describe the design of an ultrawideband balun using a multiaperture ferromagnetic core. The balun is designed to operate over several decades of bandwidth to provide a broadband solution to an increasingly complex spectrum. This design is intended for receiver front-end applications where wideband performance is a critical device requirement. The characteristics of the ferromagnetic material and unique design arrangement provides state-of-the-art insertion loss performance when compared to commercially available baluns.
