Abstract :
Studies a high temperature superconducting (HTS) lumped element resonator consisting of an inductance and capacitance in parallel. It has a low power unloaded quality factor Q0 in excess of 9000 at 5.7 GHz and 1 K. The resonator is just over 1 mm square, significantly smaller than any other device with comparable Q at this centre frequency. The authors also investigate the implementation of the resonator in a bandstop filter.
