前言根据空间技术发展的要求,为确保雷达和通讯等电子设备对快速飞行目标进行精确地测控,并可靠地传递信息,均要求电子设备的工作频率具有短期取样的高稳定性,即要求用于主控频率源的晶体振荡器具有相应的特性。为要获得短稳高(或噪声低)的“晶振”,除了要合理的设计并采用低噪声的电路外,还基于选用高性能的石英谐振器。本文着重对石英谐振器的这种运用机理作了分析,引述并解析了“响应带宽”及“内调制”的物理概念及表微式,为研究适应于短稳应用的石英谐振器提出了笔者的见解及合理设计的依据。
Preface According to the requirements of the development of space technology, to ensure accurate measurement and control of fast-moving targets by electronic equipment such as radar and communications and to reliably transmit information, the operating frequency of electronic equipment is required to have high stability of short-term sampling, that is, The crystal oscillator of the master frequency source has the corresponding characteristic. In order to obtain the “crystal oscillator” with short stability (or low noise), it is also based on the selection of a high-performance quartz resonator in addition to a reasonable design and use of a low-noise circuit. This paper focuses on this mechanism of quartz resonator is analyzed, quoted and analyzed the “response bandwidth” and “internal modulation” of the physical concept and table micro-mode, to adapt to the short-term application of the quartz resonator proposed author Opinions and reasonable design basis.
