A broadband slot line non reciprocal microwave device which comprises a matched load placed on the face of a ferrite plate which is located within the microwave magnetic field of the slot line, said face being opposite to said slot and designed so that its height is larger than 3 times the width of the slot and its length is at least equal to a half wavelength as propagated within the slot at the maximum operating frequency. Said matched load may be a second slot line or a lossy ferrite plate. The device operates as an isolator with more than 20 dB isolation. It can be designed as a four port circulator.
