本文讨论尾部警戒雷达方案中所采用的石英振荡器的设计和研制。在经过改进的比例控制恒温器中使用 SC 切晶体已获得极好的加热特性。仅五分钟后,稳定度达到1×10~(-8)。该振荡器工作在10兆赫,利用 TO-8型外壳的三次泛音 SC 切晶体。缩小了比例控制恒温器的尺寸,以便得到快速加热所需的最小质量。本文介绍该振荡器的结构和电路设计,并讨论加热、温度稳定性和其它特性的测试结果。文章介绍了有关 SC 切晶体对“g”灵敏度和辐射灵敏度的附加数据。辐射数据表明,稳定度比用 AT 切晶体的要高1-2个数量级。 This article discusses the design and development of the quartz oscillator used in the tail guarded radar program. The use of SC-cut crystals in an improved proportional-controlled thermostat has achieved excellent heating characteristics. After only five minutes, the stability reached 1 × 10 -8. The oscillator operates at 10 MHz using triple harmonic SC cut crystals of TO-8 type housings. The size of the proportional control thermostat is reduced to get the minimum mass required for rapid heating. This article describes the oscillator structure and circuit design, and discusses the heating, temperature stability and other characteristics of the test results. The article presents additional data on “g” sensitivity and radiation sensitivity for SC-cut crystals. Radiation data indicate that the stability is 1-2 orders of magnitude higher than with AT cut crystals.
