Abstract :
The design and development of a 13.3 GHz three-pole Chebyshev bandpass filter using a YBa2Cu3O7- delta thin film on an MgO substrate is described. An insertion loss of 0.2 dB at the centre frequency and an unloaded Q of 2800 are obtained at 77 K. The measured characteristics are better than other high-temperature superconductor planar filters so far reported.
