A 4-pole Chebyshev band-pass filter with the center frequency 5.0 GHz and the 0.01 dB-ripple fractional bandwidth 3.2% is designed based on the theory of direct-coupled resonator filters using K- and J-inverters. This filter is fabricated by using a high-T_c superconductive YBCO film deposited on a MgO dielectric substrate. The frequency response of the filter measured at 60 K agrees very well with the theoretical one. The insertion loss is 0.22 dB. The insertion loss of this filter is the lowest in HTS-CPW filters presented so far., copyright(c)2002 IEICE 許諾番号:07RB0174, text, application/pdf}, pages = {714--719}, title = {A Low-Loss 5 GHz Bandpass Filter Using HTS Quarter-Wavelength Coplanar Waveguide Resonators(<特集>Special Issue on Superconductive Electronics)}, volume = {E85-C}, year = {2002}, yomi = {スズキ, ヒデユキ and マ, テツオウ and コバヤシ, ヨシオ} }
