Ionizing space radiation effects on surface acoustic wave resonators

Two available types of single pole 199 MHz SAW resonators were irradiated to determine space radiation performance, some fabricated on air-swept 40 degrees Y-rotated quartz substrate, and some fabricated on non-swept quartz. In addition, some of the resonators on non-swept quartz were coated with 40...

Beschreibung
Zusammenfassung:	Two available types of single pole 199 MHz SAW resonators were irradiated to determine space radiation performance, some fabricated on air-swept 40 degrees Y-rotated quartz substrate, and some fabricated on non-swept quartz. In addition, some of the resonators on non-swept quartz were coated with 400 AA RF sputtered layer of SiO/sub x/. It was found that sensitivity to radiation is substrate material dependent, with pure substrates showing less radiation degradation in performance. An unexpected reduction in sensitivity was found for the coated devices.< >
