  • Abstract
    The transducer electrodes of high frequency surface acoustic wave (SAW) devices can be damaged by dc voltage transients as low as 150 volts. Controlled dc pulsed voltage levels applied to SAW device aluminum interdigital electrodes on piezoelectric quartz and lithium niobate have served to define arc discharge and surface fracture conditions affecting device performance. It is recommended that high frequency SAW devices be handled as voltage sensitive parts.
