Abstract
The present invention is directed to a surface mountable circulator/isolator device that includes a first dielectric layer having an electric circuit formed thereon. A second center dielectric layer is disposed adjacent the first dielectric layer, the center dielectric layer including an opening formed therein, the opening being aligned relative to the electric circuit. A ferrite element is disposed in the opening such that the ferrite abuts the electric circuit and is aligned in two-dimensions relative to the electric circuit. A third dielectric layer is disposed adjacent the second center layer. The third dielectric layer includes a ground plane formed on each major surface thereof. The first dielectric layer, the second center dielectric layer, the ferrite element, and the third dielectric layer are bonded together to form a laminated multi-layer structure. A permanent magnet is bonded to the second ground plane.
