Paper Abstract

High Q resonators are a critical component of stable, low-noise communication systems, radar, and precise timing applications such as atomic clocks. In electronic resonators based on Si integrated circuits, resistive losses increase as a result of the continued reduction in device dimensions, which decreases their Q values. On the other hand, due to the mechanical construct of bulk acoustic wave (BAW) and surface acoustic wave (SAW) resonators, such loss mechanisms are absent, enabling higher Q-values for both BAW and SAW resonators compared to their electronic counterparts.1 The other advantages of mechanical resonators are their inherently higher radiation tolerance, a factor which makes them attractive for NASA's extreme environment planetary missions, for example to the Jovian environments where the radiation doses are at hostile levels.2 Despite these advantages, both BAW and SAW resonators suffer from low resonant frequencies and they are also physically large which precludes their integration into miniaturized electronic systems.
