Abstract

Band-pass filters with dielectric resonators of (Zr_0.8Sn_0.2)TiO₄ ceramic materials (ZST) were developed for X-band applications. The ZST materials exhibit a dielectric constant of about 36.8 and low loss in microwave range. A Qxf product higher than 50.000 was achieved for the ZST samples with 0.2% wt NiO sintering addition. The external coupling was performed using microstrip lines on a substrate of 9.22 dielectric constant and 0.635 mm height. Filters with minimum insertion loss between 0.46 dB and 1.74 dB. the bandwidth between 40 MHz and 170 MHz and with the central frequency around 10 GHz were manufactured.
