Magnetically tunable wideband magnetostatic-surface-wave filter using Ga-YIG film
Abstract
The characteristics of a magnetically tunable wideband filter utilizing the property of a pass bandwidth of magnetostatic surface waves (MSSW) are given. The pass bandwidths of MSSW obtained experimentally through the Ga-YIG slab having the saturation magnetization, 1100 Gs and the ordinary transducers consisting of wire antenna vary from 230 to 55 MHz for the operation frequency, 1 to 8 GHz, corresponding to the external static magnetic field. These results could fully be explained by the theory. Loaded Q values of this filter vary from 20 to 270 at the same frequency range as above.
