<p>Circulator and method of making that includes the steps of providing a central substrate (11) with at least one cut-out section (14) and circuit lines (12). A magnet (10) is placed within the cut-out section (14). Ferrites and steel plates are placed on each side of said substrate layer. Also, spacer layers and outer shim layers are provided on each side of the substrate layer. Laminate sheets are placed between the substrate layer, the spacer layers, and the outer shim layers. Holes are drilled through each of these layers/sheets. Heat and pressure cause the laminate sheets to flow to join the substrate, magnets, ferrites, steel plates, spacer layers, and outer shim layers into a unitary structure that is finally plated.</p> |
