Abstract (en)

[origin: US4808949A] A hyperfrequency circulator is provided in which the gyrator is integrated in the wave-guide, comprising a wave-guide whose two main faces are pierced with two holes, aligned with the center of symmetry of the junction. Through these holes a one-piece gyrator passes formed by at least one magnet, a pole piece, a solid dielectric resonator and a second pole piece. The gyrator is cylindrical in shape, and the pole pieces each have a flange of the same diameter as the holes in the wave-guide, the cooling plates immobilizing the one piece gyrator in the wave-guide.
