1. A device for attenuating microwave signals above a preselected power level passed therethrough comprising:
- a pair of planar ferrite members;
a plurality of signal-carrying conductors positioned between said ferrite members for carrying the microwave signals on an axis substantially parallel thereto; and
a planar ground plane surrounding the ferrite members in spaced relation with respect to the conductors by a selected distance, said signal carrying conductors being separated by at least ten times the distance from the ground plane to the conductors such that microwave field coupling between adjacent conductors is negligible.

Abstract
A frequency selective limiting device is described incorporating a pair of generally planar ferrite members and a plurality of signal-carrying conductors positioned between the ferrite members. The plurality of signal-carrying conductors are located on a single YIG substrate. A D.C. bias field may be generated by a common magnetic source positioned on the surface of the substrate opposite the plurality of signal-carrying conductors.
