High-Selection Integrated Filters on the Basis of HTSC-Films for Microwave Receivers of Satellite and Cellular Communication Systems, Radiolocation and Radioastronomy

Description

High-selection microwave integrated filters on the basis of high-temperature superconductors (HTSC) YBCO-films. Performances of integrated filters on the basis of HTCS YBCO-films:

  • Operating temperature: –––––––––––––––––––––––––––– < 83К;
  • Center frequency f0: –––––––––––––––––––––––––––––– 1 – 4 GHz;
  • Bandpasswidth: –––––––––––––––––––––––––––––––––– 2 – 5 % f0;
  • Losses in the passband: ––––––––––––––––––––––––––– < 1 dB, < 0.5 dB;
  • Steepness of passband boundary: ––––––––––––––––––– 2-8 dB/MHz;
  • Losses outside of the passband: –––––––––––––––––––– at 0.1 f0 > 45 dB;
  • TC YBa2Cu3O7-δ -films: ––––––––––––––––––––––––––– 89К.
