The loss tangent for a circular cavity resonator is 0.0004.Then the unloaded Q due to dielectric loss is: Correct Answer 2500

Unloaded Q due to the dielectric loss in a circular cavity resonator is the reciprocal of the loss tangent. Hence, taking the reciprocal of the loss tangent, unloaded Q due to dielectric loss is 2500.
