13.3 GHz YBCO microstrip bandpass filter
The design and development of a 13.3 GHz three-pole Chebyshev bandpass filter using a YBa2Cu3O7−δ 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 ...

Microwave Diplexer Purely Based on Direct Synchronous and Asynchronous Coupling [PDF]
A diplexer realized purely based on direct coupling is presented. No cross-coupling is involved in the design process. The microwave diplexer is achieved by coupling a dual-band bandpass filter onto two individual channel filters.
