Additive Manufacturing of Magnetic Materials to Improve RF Circuitry
While active components have gotten smaller, the past few decades have seen little improvement in the size of passive integrated circuit components. By decreasing the size and increasing the functionality of these components, integrated circuits can become smaller, faster, and cheaper. Low-cost additive manufacturing of ferromagnetic inks for RF integrated circuits provides a promising opportunity to improve these large components. The 2017-18 Raytheon SCOPE team fabricated and tested additive manufactured ferromagnetic inks on passive RF circuit components. A complex RF circuit was used to demonstrate the effects of this emerging technology.
