利用共面波导 (CPW) 四分之一波长谐振器设计了高温超导 (HTS) 5 GHz 10 极带通滤波器 (BPF)。 10 极切比雪夫 BPF 的中心频率为 5.0 GHz，分数带宽为 3.2%。基于 J 和 K 逆变器的等效电路，首先使用 EM 模拟器设计滤波器。接下来，采用优化算法来诊断 EM 模拟器计算出的滤波器响应与等效电路之间的差异。由此调节过滤器的尺寸。调整后的滤波器的频率响应很好地满足设计指标。
A high temperature superconductor (HTS) 5 GHz 10-pole bandpass filter (BPF) is designed by using coplanar waveguide (CPW) quarter-wavelength resonators. The 10-pole Chebyshev BPF has a center frequency 5.0 GHz and a fractional bandwidth of 3.2%. Based on an equivalent circuit with J- and K-inverters, the filter is first designed by using an EM simulator. Next an optimization algorithm is employed to diagnose the discrepancy between the filter response calculated by the EM simulator and the equivalent circuit. Adjustment of the dimensions of the filter is made thereby. The frequency response of the adjusted filter well satisfies the design specifications.
