摘要

介绍了一种室温频率-温度补偿双模谐振振荡器(专利申请中)的频率稳定性分析。利用直径40 mm、高20 mm的单晶圆柱形蓝宝石谐振腔，在304 K附近同时激发两个正交极化的窃窃廊模式，差频温度依赖性消除。测量到两种模式之间3.39 GHz拍的标准艾伦偏差在1和4s之间约为8 /spl倍/ 10/sup -12/。

Room temperature dual-mode oscillator - first results

A frequency stability analysis of a room temperature frequency-temperature compensated dual-mode resonator oscillator (patent pending) is presented. Using a single crystal cylindrical sapphire resonator, 40 mm in diameter and 20 mm high, two orthogonally polarized whispering gallery modes were simultaneously excited, with the difference frequency temperature dependence annulled near 304 K. The standard Allan deviation of the 3.39 GHz beat between the two modes was measured to be approximately 8 /spl times/ 10/sup -12/ between 1 and 4s.
