本文讨论在超高频下利用声波振荡器直接获得良好频谱质量和热稳定性。并介绍两种不同类型的声波振荡器的设计和性能。在微波领域巾通常要求不需高压、使用低功率及高温稳定性的小型、可靠的频率源。最近的研究指出:声波振荡器是满足这种要求的很好的候选产品。两种不同类型的声波振荡器是能实现的:一种是使用ST一切石英上的声表面波延迟线;另一种是利用特殊晶休介质的 This article discusses the direct use of sonic oscillators to achieve good spectral quality and thermal stability at UHF frequencies. Describes the design and performance of two different types of sonic oscillators. In the field of microwaves, a small, reliable frequency source that typically requires no high voltage, low power, and high temperature stability is required. Recent research indicates that sonic oscillators are good candidates for meeting this requirement. Two different types of sonic oscillators are achievable: one is the use of ST-all quartz SAW delay lines; the other is the use of special crystal-dielectric
