Abstract
Microstrip resonators fabricated from thallium high-temperature superconducting thin-films have been demonstrated to have loaded Q values in the 8000 to 20000 range at frequencies up to X band. The resonators are used as the stabilizing elements in low-phase-noise microwave oscillators. Results in oscillators using TlBaCaCuO superconducting thin-film resonators and low-noise GaAs FET amplifiers operating at frequencies of 2.3 GHz and 10.2 GHz are presented. These superconducting oscillators demonstrate improved performance over conventional dielectric resonator oscillators operating at the same frequencies.Keywords
