Abstract

A shielded dielectric rod resonator operating with the TE_01δ> mode which is constructed,by centering a sapphire rod in a cylindrical conducting cavity is designed to obtain the maximum value of Q-factor due to the Conductor loss.The unloaded Q,Q_u value calculated for this resonator constructed with a YBCO superconducting cavity is about three times as high as that for a TM_01δ> mode high-Q dielectric rod resonator which is constructed by centering a low-loss BMT ceramic rod with relative permittivity of 24 in a YBCO superconducting cavity,at.12GHz and 77K.When a measured values for this sapphire resonator were Q_u= 144,000 and a temperature coefficient of resonant frequency,τ_f=-6.6ppm, K at 9.8GHz and 77K.
