Research Abstract

The purpose of this study was developing a superconducting transmit filter with the best performance. We designed and fabricated the 3-pole filter using the superconducting bulk ring resonators and observed the power-handling capability (PHC) more than 25 W. Moreover, we estimated the PHC of 3-pole filter using the disk resonators more than 100W by the electro-magnetic field simulation. It was also found that the 9-pole cross-coupling filter was needed to obtain the sharp skirt properties and we could design and fabricated 2- and 3-pole filters.
