摘要

我们介绍了基于蓝宝石“窃窃廊”模式谐振器的低相位噪声信号发生器的最新进展，并展望了这些振荡器的未来潜力，以满足日益增长的精密信号产生和处理需求。除了改善相位噪声性能外，未来的振荡器将需要在更苛刻的温度范围内工作，具有更低的振动灵敏度和更高的可靠性。我们讨论了蓝宝石振荡器的性能，特别是在室温附近工作的蓝宝石振荡器，并介绍了最近的振动灵敏度小于10/sup -10/每g，相位噪声在10.24 GHz载波的1 kHz偏移时为-146 dBc/Hz，在10 kHz偏移时为-170 dBc/Hz，以及扩展温度工作。

A review of sapphire whispering gallery-mode oscillators including technical progress and future potential of the technology

We present the results of recent progress in the development of low phase noise signal generators based on sapphire "whispering gallery"-mode resonators, and look at the future potential of these oscillators to meet the ever-increasing demands for precision signal generation and processing. Beyond improving phase noise performance, future oscillators will be required to work over more demanding temperature ranges, with lower vibration sensitivity and greater reliability. We discuss the performance of sapphire oscillators, particularly those operating near room temperature, and present recent results of vibration sensitivity less than 10/sup -10/ per g, phase noise of -146 dBc/Hz at 1 kHz offset and -170 dBc/Hz at 10 kHz offset from a 10.24 GHz carrier, and extended temperature operation.
