Abstract

This paper presents a five pole Chebyshev 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
