Abstract
A frequency selective limiter is described in which first and second ferrite members have confronting planar surfaces and at least one conductor is located on the surface of each ferrite in intimate contact. Each conductor on the first ferrite is a mirror image and is paired to a corresponding conductor on the second ferrite. The paired conductors have confronting end surface portions which are intimately bonded or welded in electrical contact such that each of the paired conductors is electrically equivalent to a single conductor in closely coupled to the ferrites. No other form of bonding is necessary to secure the ferrite members together. In the invention, an external conformal ground plane is more securely deposited in the regions where the ferrites abut. In a particular embodiment, coplanar ground planes located between the ferrites are securely bonded to the conformal ground plane.
