  • Co-firing of magnetic and dielectric materials for fabricating composite assemblies for circulators and isolators
    Patent number: 7687014
    Abstract: A method for making a composite magnetic-dielectric disc assembly includes forming a dielectric ceramic cylinder, forming a magnetic ceramic rod, assembling the magnetic ceramic rod coaxially inside the dielectric ceramic cylinder to form a rod-and-cylinder assembly, kilning (firing) the rod-and-cylinder assembly, slicing the rod-and-cylinder assembly to form a plurality of composite magnetic-dielectric disc-shaped assemblies. The magnetic-dielectric disc assemblies can be used in manufacturing, for example, circulators, isolators or similar electronic components. Accordingly, the method for making the disc assemblies can be included as part of a method for making such electronic components.
