ABSTRACT:
A ferrite stripline circulator having low cost, broad tolerance elements and an easy to assembly design. The unit comprises of a cylindrical housing into which are stacked a ferrite disk, a center conductor, another ferrite disk, a metal ground plane, a disk magnet, a metal cover and a compression spring. A C-clip, that fits into a groove on an upper inner circumference of the cylinder, forces the compression spring against the cover and thereby applies the pressure that is required to assure proper operation of the stacked elements.
