A new sapphire TE10δ resonator was constructed with a novel support structure made from sapphire and rutile (patent pending). The amount of rutile was chosen to act as Bragg reflectors to reduce conductor losses while simultaneously annulling the temperature coefficient of frequency. The resonator was confirmed to have an annulment temperature of −8°C and Q-factor of 65 000 limited by the dielectric loss tangent.
