摘要
The superconducting band-pass filter has small insertion loss and excellent out-of-band rejection properties. It has been put to practical use in a number of applications. However in order to expand its range of application, a tuning, technique that can restore the filter characteristics is needed. We propose an automatic tuning system using a trimming library and checked the feasibility of the system by lulling a forward-coupled filter with three resonators. The results show that the trimming library method is an effective way of automatically improving the filter characteristics.
