Abstract
Sapphire single crystal, associated with a special mode
configuration (whispering gallery mode), is an ideal material for the
realisation of high Q microwave resonator. Unfortunately, the frequency
sensitivity to temperature fluctuations is relatively high. With such a
sensitivity it is impossible to reach high frequency stability over a
long time interval without efficient temperature regulation. We
implemented original thermal regulation scheme on different sapphire
resonators. We report, in this paper, frequency stability measurements
of temperature controlled sapphire resonator oscillator at room
temperature and at liquid nitrogen temperature
