本文报道了一种在宽带旋转器上实现片上隔离器或环行器的概念验证实验。提出了一种新的回转器结构，该回转器由两个超导-绝缘体-超导体(SIS)混频器和两个相位延迟电路组成，以减小回转器的尺寸并扩展其工作频带。利用现有的波导型SIS混频器研究了有利于回转器工作的工作频率、带宽和传输特性。此外，还讨论了对传输特性有很大影响的边带对消。在本实验中，虽然在两个SIS混频器之间插入了一个6分贝的衰减器，但回转器的S21和S12的平均幅度在0.0 1-5.0 0 GHz范围内约为−3分贝。此外，在0.10-5.00 GHz范围内，S21和S12之间的相位差为180±10°，表明该结构作为回转器工作。
This article reports a proof-of-concept experiment on a wideband gyrator to realize an on-chip isolator or circulator. We propose a novel configuration of the gyrator composed of two superconductor–insulator–superconductor (SIS) mixers and two phase-delay circuits to downsize the gyrator and extend its operating frequency bandwidth. The operating frequency bandwidth and transmission characteristics that facilitate gyrator operations are investigated using existing waveguide SIS mixers. In addition, sideband cancellation, which considerably affects the transmission characteristics, is discussed. Although a 6 dB attenuator was inserted between the SIS mixers in this experiment, the average magnitude ofS21andS12of the gyrator was found to be approximately −3 dB in the range of 0.01–5.00 GHz. In addition, the phase difference betweenS21andS12is 180 ± 10° within 0.10–5.00 GHz, indicating the operating of this configuration as a gyrator.
