Abstract

Two X-band oscillators have been designed, built, and tested. Superconducting films of both Y₁Ba₂Cu₃O_x (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
