ABSTRACT:
A plurality of frequency selective limiting units are prepared on a common substrate. A plurality of generally linear signal carrying conductors are formed in spaced relation on a first ferrite member, the opposite side of which contains a lower ground plane. A second ferrite member is bonded to the first ferrite member with a nonconductive adhesive to form a layered structure. Grooves are formed in a free surface of the structure to a depth sufficient to cut through the first and second ferrite members and to expose the lower ground plane. The structure is metallized in a conformal manner so that the metallization is in contact with the lower ground plane. The units are separated by dicing to thereby provide a plurality of individual FSL's.
