The filter was simulated by a finite element method software and then fabricated using TBCCO superconducting films on 20 mm×20 mm×0.5 mm MgO substrates. It was generated by photolithographic and wet etching process and packaged in a brass box. The bandwidth is 4% and the passband insertion loss of the filter was measured to be -0.4 dB at 77 K. The return loss is better than -8 dB. In particular, this filter has a sharper performance at its edge of fundamental pass band A miniaturized interdigital microstrip bandpass filter Kao-Cheng Huang D Hyland A Jenkins D Edwards D Dew-Hughes Applied Superconductivity, IEEE Transactions on, Vol. 9, No. 2.
