ABSTRACT:
A compact multi-junction ferrite circulator/isolator in which ferrites, junctions with center conductors and permanent magnet are situated in a stacked manner with common center line within non-magnetic housing. A magnetic circuit also has C-shaped members each having shield, return and ground plane portions. The permanent magnet is located in between the ground plane portions of two C-shaped members. In this tandem circuit one permanent magnet and two ferrites having cross section area of those in a single circuit and less expensive round ferrite shape might be used. It gives a uniform magnetic flux which, in turn, provides better tandem circuit properties. The stacked situation of all principal tandem circuit members also gives the best horizontal integration. Vertical portion of a dielectric film within the tandem circuit might be used for a communication line application, for example, for an amplifier giving the highest level of integration.
