MEASUREMENT OF LINEWIDTH OF SINGLE CRYSTAL FERRITES USING A SHORTED TRANSMISSION LINE.

Abstract

A technique is described for measuring the linewidth of single crystals of ferrites which is accurate, rapid, easy to use, and can be readily adapted to give a visual display of the resonance curve. At C-band, the normalized equivalent resistance due to the ferrite sphere at resonance (expressed as a parallel component) agrees well with theory whether the sphere is undercoupled, critically coupled, or overcoupled to the transmission line. However, a substantial reactive component is present when the sphere is near critical coupling or overcoupled, and this is contrary to theory. It is concluded that measurement of linewidth should be taken under conditions where the sphere is substantially undercoupled.
