Bulk acoustic wave (BAW) resonator technology
Enable ultra-low jitter and superior reliability for next-generation timing solutions
What is BAW?
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.
Why choose our BAW technology?
Enable industry-leading jitter performance
Integration of our BAW technology into our network synchronizer products enables ultra-low jitter performance of 42 fs.
Built for reliability
BAW technology enables high resiliency to harsh environmental conditions such as mechanical shock and vibration and achieves 100x better MTBF compared to quartz-based solutions.
Manufacturability
Our manufacturing process, including fabrication, assembly and packaging, mitigates supply concerns with an integrated solution that enables faster sampling and shortened lead times.
Simplify your design
Utilize the integration of BAW into low-power wireless MCUs and clock generators to remove the need for an external crystal or oscillator, resulting in a reduction in BOM, cost and space.

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.
