Abstract: Approaches to producing modular electronic packages include modular arrangements that operate from DC up to 110 GHz and are presented using additive manufacturing such as 3D printing and laser-machining. A method includes assembling electrical circuits from circuit components positioned on modular substrate sections by identifying respective positions of selected components of the electrical circuits on an original substrate; mapping a cut path across the original substrate, wherein the cut path is determined by the respective positions of the selected components; cutting the original substrate along the cut path, wherein the cut path separates the selected components of the electrical circuits onto substrate pieces defining respective side portions; and mating the respective side portions of the respective substrate pieces with corresponding side portions of other substrate sections to assemble the electrical circuits across substrate junctions.

Abstract: A soft ferrite composition comprises a ferrimagnetic ceramic material having a crystal structure and a dopant in the crystal structure, wherein the ceramic material comprises an oxide including nickel, cobalt, zinc, and iron, wherein the dopant is selected from the group consisting of copper oxides, and wherein the dopant is present in the crystal structure at 0.1 to 20 weight percent based Non a total weight of the composition. The dopant can be CuO. The copper oxide doped Ni—Co—Zn ferrite can be used for very high frequency (VHF) and ultra high frequency (UHF) applications such antennas, isolators, and circulators.
