Abstract
The results of phase noise measurement for high-overtone bulk-acoustic resonators (HBARs) for use in high-performance oscillators, operating at 640 MHz with insertion losses of 10-15 dB and unmatched Qs greater than 110 K are reported. Noise measurements made on these resonators with input drive levels of 16 dBm have shown self-noise levels of S/sub y/(f=100 Hz)=8.0*10/sup -26/ for 1/f noise which represents state-of-the-art for a UHF resonator.<>Keywords
