We have fabricated and tested RF SQUIDS made of Nb and YBa 2 Cu 3 O 7 (YBCO), a high‐temperature superconductor, at 10 GHz using TE 011 mode cavities and HTS microstrip resonators. Devices were screened at 27 MHz, and subsequently evaluated at 10 GHz. The SQUID circuit parameters, k 2 Q and β, were determined at different temperatures.
