Abstract :
Two X-band oscillators have been designed, built, and tested. Superconducting films of both Y1Ba2Cu3Ox (YBCO) and Tl2Ba2Ca1Cu2O1 (TBCCO) were used. The films were grown by laser ablation. A resonator was patterned in each of the high-temperature superconducting (HTSC) films to stabilize two X-band oscillators. The reaction-type oscillator uses a YBaCuO HTSC ring resonator and the parallel feedback oscillator uses a thallium-based HTSC half-wavelength resonator with an unloaded Q=21000. The design and development of these oscillators and characteristics of HTSC resonators are discussed
