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 uses piezoelectric transduction to generate a gigahertz frequency and high-Q resonance that can be integrated directly into standard plastic packages that contain other integrated circuits. BAW provides many advantages over traditional quartz and micro-electro mechanical 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.

Upgrade your design with BAW technology

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.
