Abstract :
The dc magnetic field dependence of rf permeability in ferrite, the deviations of resonance dc magnetic field and its half-width in a ferrite disk, and the destruction temperature difference of the ferrite disks are measured in order to select the ferrite material and disk for high-power microwave circulator. Also demonstrated are the design and performance of a newly developed multi-layered junction circulator with a power handling capability of CW 250 KW at 500 MHz band.
