Summary: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.
