| Abstract: | The design and development of a 13.3 GHz three-pole Chebyshev bandpass filter using a YBa/sub 2/Cu/sub 3/O/sub 7- 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.<> |
