Abstract

This article presents a six‐pole high‐temperature superconducting (HTS) filter with a fractional bandwidth (FBW) of 0.09% at 3.3 GHz. Twin‐spiral resonators with a high quality factor (Q~u~) of 69,000 are used in the design procedure. The measured results of the filter exhibit a low insertion loss of 0.62 dB and are in good agreement with the simulated ones. © 2010 Wiley Periodicals, Inc.
