S. G. Souchkov, D. S. Chaikovsky Saratov State University
Abstract:
Effect of the thickness and elastic properties of sublayer chrome and vanadium of two-layer metallic film, from which the electrode structure is formed, on thermostability of SAW devices in the microwave band is investigated. Angles of the thermostable Y-cuts for the frequencies 1 and 2 GHz are found. Also reflection factor of SAW from edges of electrodes IDT is investigated. Thickness of aluminium and chrome in two-layer electrodes at which the reflection factor is equal to zero are found.
Keywords:
surface acoustic waves, electrode structure.
