Abstract
An improved electronic structure for achieving a frequency offset between two or more YIG devices tuned by a single electro-magnet. The structure does not require different sizes of YIG spheres, different magnet gap spacings, or modified coil windings on the electro-magnet, but relies entirely upon the anisotropy variations of the single crystal structure of the YIG spheres when they are mounted on respective tuning rods on a specific axis and rotated under a variable field for a fixed frequency input.
