Abstract
A microwave ferrite circulator has a conductive junction with three equal angular conductors connected to serve as ports of the circulator. Ferrite plates are positioned on opposite sides of the conductive junction. Magnetic members form a magnetic coupling path between a permanent magnet and the ferrite plates. A bimetal strip is positioned in the magnetic coupling path between the magnet and the ferrite plates for altering the coupling as a function of temperature to thereby compensate for changes in tuning due to changes in temperatures of the circulator.
