| Abstract: | A novel shuttle-shape microstrip resonator for high-power high-temperature superconductor (HTS) filters is presented. By transmission
line theory analysis, it can improve the power handling capability up to 20%, depending on the configuration of the resonator.
To confirm this analysis result, two 2-pole HTS filters based on shuttle-shape resonator and rectangle resonator were simulated.
Considering the limitation of computer memory, a moderate configuration was chosen for HTS filter design. By computer simulation,
a comparison between filters with shuttle-shape and rectangle resonators showed a 10% increase in power handling capability.
The HTS shuttle-shape filter was fabricated and tested. It has a center frequency of 2022 MHz with a 2.5% bandwidth. The measured
power level was over 34 dBm at 70 K with sufficiently low insertion loss. |
