    摘要: A planar phase shifter formed of multiple layers of a ferrite. Selected layers of the ferrite are patterned with a conductor and the multiple layers of magnetic dielectric and conductor are cofired. The phase shifter is fabricated by first obtaining ferrite powder. Then, layers of the ferrite are made, preferably by tape casting. Next the ferrite layers are metallized by applying selected amounts of conductive metals in a selected pattern upon the tape. Selected numbers of vias are placed through selected layers of tape and conductive metal is placed in the vias to provide vertical connections through the layers. The tape layers are then stacked in a predetermined order and are laminated. The laminated stack of layers is then fired to a temperature of approximately 800.degree. C. to 1000.degree. C., sintering the laminated layers into one integrated structure.
