V. M. Pan, V. F. Tarasov, N. A. Skorik, S. I. Futimsky


The paper discloses advantages of usage of films made of high-temperature superconductors for creating various microwave devices. The quality factor of an asymmetric strip resonator of film design is estimated at frequency 2 GHz and at 77 K (liquid nitrogen temperature). Frequency responses of a nine-resonator band-pass filter designed with the use of films are included. The advantages of application of high-temperature superconducting films for new generations of microwave devices are outlined.
