Abstract

In the pursuit of on-chip superconducting non-magnetic non-reciprocal devices, several designs have emerged, yet their development has lacked a unified approach, complicating the early design stages. We addressed this by building a circuit model of superconducting components in Advanced Design System (ADS) and simulating a superconducting isolator using the harmonic balance (HB) method. Our model's accuracy was validated through comparison with experimental data. The designed superconducting isolator achieved

- 20 dB

isolation, a bandwidth of less than

500 MHz

, and an insertion loss of

5 dB

. This demonstrates the strong potential of our method in the design of superconducting microwave devices.
