Abrégé
Disclosed is a non-reciprocal microwave component that includes three waveguides and a central resonator (6) having upper walls (12) and lower walls (14) around a resonance volume (10), each waveguide having an electromagnetic wave propagation zone, the central resonator and the waveguides being arranged so that electromagnetic waves circulate between the resonance volume and the propagation zone of the waveguides, and wherein: the upper and lower walls have upper conductive surfaces (26) and lower conductive surfaces (28) oriented towards the resonance volume and facing each other; the central resonator comprises two elements, one ferromagnetic and the other ferromagnetic or dielectric (15A, 15B), in the resonance volume, staggered in a direction (Z-Z) orthogonal to the upper wall and separated by a dielectric layer (30), one element being in contact with the upper conductive surface and the other element being in contact with the lower conductive surface.

Abrégé
Disclosed is a non-reciprocal microwave component (2) that comprises three waveguides having a propagation zone, and a central resonator comprising upper and lower substrates (12, 14) around a resonance volume, so that electromagnetic waves circulate between the resonance volume and the propagation zones; and wherein: the upper and lower substrates comprise a dielectric layer (16) having outer and inner faces (18, 20) covered with outer and inner conductive layers; vias (26) extend between and in electrical contact with the outer and inner conductive layers of the upper substrate at connection points; the connection points (28) of the inner conductive layer enclose a free surface of the inner face of the dielectric layer, the free surface not being covered by the inner conductive layer; and a single magnetized ferromagnetic ceramic element (15) is placed between the free surface of the upper substrate and the lower substrate.
