Abstract

Design and performance of miniaturized coplanar waveguide (CPW) bandpass filters (BPFs) using high Tc superconducting (HTS) films have been studied. In order to realize the miniaturized filters, we coupled highly packed meanderline half-wavelength resonators with interdigital gaps, where admittance inverters (J inverters) were made of interdigital gaps. The exact J values, susceptance slope parameters and the length of the resonators of the meanderline are calculated from the cascade matrix (K-matrix) and scattering matrix (S-matrix) obtained by the 2.5-dimensional electromagnetic field simulator (HP-Momentum). It is shown that the size of the filters can be greatly reduced by introducing CPW with highly packed meanderline geometry (center frequency 2GHz, fractional band width 15MHz, ripple 0.1dB) packed within 10mm square substrate. Simulated performance was in good agreement with the designed one.
