Abstract: This paper presents an experimental investigation on the nonlinear characteristics of a high-temperature superconducting (HTS) dual-band bandpass filter (DBPF) that has two passbands and comprises a coplanarwaveguide quarter-wavelength resonator with odd- and even-mode resonant frequencies. An HTS filter is a potential candidate for an RF multi-band bandpass filter (MBPF) that has multiple passbands, which will support broadband transmission in future mobile communication systems. It is, however, indispensable to elucidate the nonlinear characteristics of the HTS-MBPF because the nonlinearity of HTS materials causes intermodulation distortion (IMD). This paper presents the IMD characteristics of a 2.0-/3.5-GHz band HTSDBPF using a YBCO thin film deposited on a MgO substrate when two tones with a 30-kHz separation are individually and simultaneously input to each passband. Experimental investigations confirm that the HTSDBPF generates different third-order IMD characteristics dependin g on how the two tones are input to the HTS-DBPF. This paper also presents a method for estimating the third-order IMD characteristics based on the measurement results. (More)
