摘要

本文报道了一种高稳定的小型化烤箱控制晶体振荡器(OCXO)，其尺寸为9.7 × 7.5 mm，由嵌入加热器的陶瓷封装组成。嵌入式加热层建立了对称的热场，实现了良好的温度均匀性，保持了烘箱的稳定性，降低了功耗。此外，SC-cut晶体被用于所提出的小型化OCXO，以进一步改善温度稳定性，老化和相位噪声。因此，这款9.7 × 7.5 mm OCXO在−40至85°C范围内实现了±3 ppb的温度稳定性。此外，我们还证明了所提出的小型化OCXO可以满足地层3E的要求。

Highly Stable Miniaturized OCXO with Heater-Embedded Ceramic Package

This paper reports on the development of a highly stable miniaturized Oven Controlled Crystal Oscillator (OCXO) in the size of 9.7 × 7.5 mm consisting of heater-embedded ceramic package. The embedded heater layer establishes a symmetrical thermal field to achieve good temperature uniformity, which maintains the oven stability and reduce the power consumption. In addition, the SC-cut crystal is utilized for the proposed miniaturized OCXO to further improve the temperature stability, aging, and phase noise. As a result, this 9.7 × 7.5 mm OCXO has achieved temperature stability of ±3 ppb across −40 to 85 °C. Furthermore, we also demonstrated the proposed miniaturized OCXO could be complied with Stratum 3E requirements.
