This paper presents a five pole Chebyshey bandpass filter using high temperature superconducting (HTS) thin films which employed the symmetrical TM010 mode of a circular patch resonator. The filter is designed with centre frequency of 12 GHz with fractional bandwidth of 0.45%. The design is fabricated using double sided YBCO thin films on a sapphire wafer of size (0.33×22.5×39.0)mm3. The achieved unloaded Q-factor of the resonators in the fabricated filter is about 6,500 giving the filter an insertion loss of about 0.8 dB at centre frequency of 12.14 GHz.
