Bulk Acoustic Wave (BAW) Oscillators for Timing Reference and Frequency Generation

Bulk Acoustic Wave (BAW) resonators offer exceptionally high quality factors (Q>1000) at multi-GHz frequencies. With such performance, BAW-based oscillators exhibit unrivaled jitter and phase noise performance. BAW resonators are also amenable to frequency pulling, which makes them ideal for ultra-low jitter VCO implementations. Furthermore, with proper stress isolation, they can exhibit outstanding frequency stability that rivals quartz crystal. This makes them an excellent choice as timing and frequency references. The combination of stability and ultra-low phase noise at a native multi-GHz frequency, makes BAW oscillators the ultimate reference for mm-wave and sub-THz frequency generation and synthesis. They can significantly simplify the LO chain while achieving an unmatched system performance.
