Abstract
The low-frequency noise of bulk- and surface-acoustic-wave (BAW and SAW) resonators at frequencies of from 100 to 600 MHz is studied. It is shown that both SAW and BAW resonators have parameter (resonant-frequency) fluctuations with 1/f power spectra with considerable intensity spreads: approximately 20 dB for SAW and more than 30 dB for BAW resonators. The phase-noise floor of 100-MHz oscillators with BAW resonators is −150 dB/Hz for a 1-kHz offset frequency. The phase-noise level of oscillators with SAW resonators at 400–600 MHz is higher by 5–10 dB (scaled to a 100-MHz carrier frequency).
