Abstract (en)
[origin: CN112385080A] An RF circulator in combination with a RF integrated circuit, the RF integrated circuit having a plurality of RF waveguide or waveguide-like structures in or on the RF integrated circuit, the RF circulator comprising a disk of ferrite material disposed on a metallic material disposed on or in the RF integrated circuit, the disk of ferrite material extending away from the RF integrated circuit whendisposed thereon, the metallic portion having a plurality of apertures therein adjacent the disk of ferrite material which, in use, are in electromagnetic communication with the disk of ferrite material and with the plurality of RF waveguide or waveguide-like structures, the disk of ferrite material being disposed in a metallic cavity.
