High-temperature superconducting microwave filters were designed for the W-CDMA communication system. Frequency responses of the filters were calculated by the electromagnetic simulator "Sonnet-em". A cross-coupled 8-pole microstrip line filter shows 1.949 GHz of center frequency and 1.04% of transmission fractional bandwidth on the LaAlO3, and 1.950 GHz of center frequency and 1.02% of transmission fractional bandwidth on the Al2O3.
