State-of-the-art phase noise performance has been demonstrated for both surface acoustic wave (SAW) resonator and delay line stabilized oscillators. The same basic feedback-loop oscillator design philosophy was applied in each case in order to achieve these results. This paper reviews the design, fabrication, component selection, and performance for an extremely low-noise SAW resonator hybrid circuit oscillator. Finally, several recent results including the flicker noise of SAW resonator devices and the vibration sensitivity of all quartz package SAW resonators are discussed in the context of potential SAW oscillator performance enhancements
