abstract = "Design and fabrication of an ultra selective 12-pole HTS band-pass filter with three pairs of transmission zeroes at finite frequencies is presented. This filter was designed to have quasi-elliptic response with 5 MHz bandwidth in the 3G communication band (a fractional bandwidth of 0.0025). The filter was fabricated on a 2 inch-diameter 0.43 mm-thick sapphire wafer with double-sided YBCO films. The measured results showed that the pass-band center frequency of the filter is 2.038 GHz at 68 K with a pass-band insertion loss of -0.67 dB and a return loss better than -15 dB. The measured filter also exhibited ultra high skirt slop of 200-300 dB/MHz and excellent out of band rejections (better than 60 dB for f-f0 > 2.7 MHz and better than 90 dB for f-f0 > 7.5 MHz, where f0 is the pass-band center frequency).",
