Abstract
A method of manufacturing a circulator comprising the steps of providing a central substrate layer with at least one cut-out section and circuit lines. Next, providing a magnet placed within said cut-out section and a ferrite placed on each side of said substrate layer. A steel plate is placed on each side of the substrate layer. Spacer layers are provided on each side of the substrate layer. Another shim layer is placed on each side of the central substrate layer. Laminate sheets are placed between the substrate layer, the spacer layers, and the outer shim layers. Holes are drilled through each of the substrate, the spacer layers, the outer shims, and the laminate sheets. Heat and pressure are provided to cause the laminate sheets to flow in order to join the substrate, magnets, ferrites, steel plates, spacer layers and outer shim layers into a unitary structure. Finally the structure is plated.
