摘要

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 x 10~(-12) between 1 and 4s.
