Abstract
An Nb/Nb2O5/PbInAu microstrip resonator of 0.4 ¿m di-electric height at 10 GHz and 4.2 K exhibited an unloaded Q of 257 with a measurement uncertainty of ±5%. This confirms the conductor losses calculated according to the Mattis-Bardeen theory. The dielectric loss factor of Nb2O5 at 10 GHz and 4.2 K is also confirmed by this measurement to be as in the subgigahertz range, namely 2.1 à 10¿3.
