FERRITE PHASE SHIFTER Russian patent published in 2000 - IPC

FIELD: microwave equipment. SUBSTANCE: device may be used for microwave circuits of regulation systems, as well as member of microwave phase shifters, attenuators, modulators. Ferrite phase shifter with lateral magnetic field has ferrite insertion, which is mounted in chamber of metal round waveguide, which wall is much thinner than its radius. In addition device has magnetic system, which is identical to stator of induction motor. Magnetic circuit of stator is made from soft conducting teeth and magnetic-flow conductive removable yoke. Thus, minimal waveguide length and minimal waveguide wall thickness is provided for low cost. This results in increased precision in manufacturing of inner and outer diameters, thus producing better electric parameters and recurrence rate for stock production. EFFECT: facilitated manufacturing, improved functional parameters. 2 dwg
