Abstract
A plurality of frequency selective limiting (FSL) units are concurrently prepared on a common substrate by depositing a first ferrite member onto a metallized surface of the substrate. The first ferrite member is formed by sputtering a first ferrite film onto the metallized surface and subsequently growing a ferrite layer thereon. A plurality of signal carrying conductors are positioned in spaced relation on the first ferrite member. A second ferrite member is deposited on top in the same manner as the first ferrite member. The overall structure is diced into individual units that are then metallized thereby providing a plurality of FLS's.
