Bulk acoustic wave (BAW) is a resonator technology that utilizes piezoelectric transduction to generate a GHz frequency and high-Q resonance that can be integrated directly into standard plastic packages that contain other ICs. BAW can provide many advantages over the traditional quartz and MEMs resonators including streamlined manufacturability, improved flexibility, better frequency stability, and ultra-low jitter as well as enhanced reliability under harsh environmental conditions such as vibration and shock.

Build a more reliable system with BAW technology
- Bulk acoustic wave (BAW) resonators offer many improvements over existing quartz and micro-electro mechanical resonator technologies. The primary improvement is the reliability of the BAW resonator in terms of vibration, shock, and mean-time-between-failure (MTBF) and failure-in-time (FIT) performance.
- BAW resonators can maintain a stability of less than 2 ppb/g with no significant jitter or frequency degradation before, during or after a vibration event.
- Under a mechanical shock of 1500 g, BAW resonators can maintain a frequency deviation <0.5 ppm and will not experience jitter degradation.
- BAW resonators have a FIT rate of 0.3 and a MTBF of 3.3 billion hours at 35°C, equivalent to 0.3 failures over 1 billion hours of operation.
