摘要：

Demand for improved short-term frequency stability of acoustic components used in high performance oscillators has been constantly increasing over the last few years. High-overtone bulk-acoustic resonators (HBARs) have shown extremely good performance in this area. The results of phase noise measurement for HBARs operating at 640 MHz with insertion losses of 10-15 dB and unmatched Q's 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(y)(f = 100Hz) = 8.0 X 10(-26) for 1/f noise that represents state-of-the-art for a UHF resonator.
