Ferrite ceramics are widely used in microwave devices to control transmission path, frequency, amplitude, and phase of microwave signals. Accurate dielectric and magnetic property measurements at the operational frequency and temperature ranges are needed for optimized development of these devices, as well as to assist in the manufacture of the ferrite itself. Both dielectric and magnetic losses must be determined. Dielectric resonator techniques at frequencies greater than the magnetization frequency can be combined with transmission line methods at lower frequencies for broadband ferrite characterization.
