In this paper we propose a two-pole varactor-tuned superconducting filter using coplanar waveguide (CPW) spiral-in-spiral-out (SISO) resonators. Novel internal and external coupling structures are introduced to meet the requirements for a tunable filter with a constant absolute bandwidth. The fabricated device has a frequency tuning range of 14.4% at frequencies ranging from 274.1 MHz to 317.7 MHz, a 3-dB bandwidth of 5.14 ± 0.06 MHz, and an insertion loss of 0.08 dB–0.70 dB. The simulated and measured results are in excellent agreement with each other. [ABSTRACT FROM AUTHOR]
