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...http://www.google.com/patents/US5023573?utm_source=gb-gplus-sharePatent US5023573 - Compact frequency selective limiter configuration
