采用螺旋不对称阶跃阻抗谐振器(SIRS)和一对并联馈线构成了一种紧凑型双频高温超导带通滤波器(BPF)。在双频段带通滤波器设计中，研究了一阶不连续螺旋不对称SIRS的谐振特性。由于其固有的特性和多径传播效应，设计了多个传输零点，以提高通带的选择性和阻带的抑制水平。为了便于演示，制作了一个工作在2.4/5.8 GHz的小型高温超导滤波器，用于无线局域网。每个通带的插入损耗分别为0.12和0.18分贝。测量结果与仿真结果吻合较好，验证了电路设计方法的正确性。最后，还测量和分析了双频高温超导滤光片在各个通带的微波非线性特性的温度特性和输入功率特性。测量结果与模拟结果吻合较好。
In this paper, a compact dual-band high-temperature superconducting (HTS) bandpass filter (BPF) is constructed by spirally asymmetric stepped-impedance resonators (SIRs) and a pair of parallel-coupled feed lines. The resonant characteristics of spirally asymmetric SIRs with one step discontinuity are investigated in the dual-band BPF design. Owing to its intrinsic characteristics and the multipath propagation effect, multiple transmission zeros are created to improve the selectivity of the passband and the rejection level of stopband. For demonstration purposes, a compact HTS filter operating at 2.4/5.8 GHz for wireless local area networks is fabricated. Measured insertion losses at each passband are 0.12 and 0.18 dB, respectively. A good agreement between the measurements and the simulations is observed, which verifies the circuit design methodology. Finally, the temperature dependence and the input-power dependence of microwave nonlinear properties of the dual-band HTS filter at each passband are also measured and analyzed. Measured results have a good agreement with simulations.
