This paper presents a design method to develop a high-power superconducting microstrip filter with different line width resonators. The linewidth of every resonator is optimized using this method to meet the same maximum current density. Thus, the power-handling capability of the five-pole filter on a limited substrate size can reach a maximum value. The design method is verified by~the electromagnetic simulation of the current density distribution. The high-power superconducting filter is designed and fabricated on a 38 mm × 30 mm × 0.505 mm LaAIO3 substrate. The maximum resonator linewidth is 7 mm, and the minimum one is 1.6 mm. The filter has a center frequency of 2006 MHz and a narrow bandwidth of 1.0%. The measured power level is up to 35 dBm at 65 K without an evident change in insertion loss. [ABSTRACT FROM AUTHOR] |
