ABSTRACT:
Disclosed is an improved ferrite circulator particularly adapted for use as an isolator in VHF and UHF transmission systems. It comprises a pair of relatively thick ground plates to which are attached three or more equally spaced coaxial connectors forming circulator ports. A pair of elongated magnetic members extend between the ground plates from opposite sides of the circulator junction to a location between the ground plates remote from the junction. A resilient permanent magnet is movable between the magnetic members at the remote location to provide simple and rapid tuning by adjustment of the permanent magnet field across the junction.
