| Abstract: | A high frequency and narrow-band high temperature superconductor (HTS) filter was designed on sapphire substrate. The 12-pole filter with a center frequency 9.7GHz and 1.2% bandwidth was simulated with full-wave electromagnetic simulation tools (Sonnet). The out-band rejection of the filter exceeds 90dB, and the pass-band ripple is less than 0.12 dB. |
