摘要

本文介绍了一种特殊的应力补偿SAW谐振器结构的研究结果，该结构在保持超低噪声特性的同时，大大提高了g灵敏度性能。然后描述并测试了集成这两个谐振器的特定振荡器结构。最终的结果是一个1GHz振荡器，在g灵敏度(所有轴均< 2.10-10/g)和相位噪声(3kHz偏移时-154dBc/Hz，本底噪声-175dBc/Hz)方面表现出前所未有的性能。

Compact ultra-low noise SAW oscillator with reduced g-sensitivity for radar applications

This document presents the results of investigation on a particular stress-compensated SAW resonator configuration allowing a strong improvement in g-sensitivity performance while keeping ultra-low noise characteristics. A specific oscillator architecture integrating two of these resonators is then described and tested. The final result is a 1GHz oscillator presenting unprecedented performances in g-sensitivity (<;2.10-10/g in all axis) and phase noise (-154dBc/Hz at 3kHz offset, -175dBc/Hz noise floor).
