Abstract

A linear phase filter using two cross-coupled quadruplet structures to achieve self-equalization was designed at 2012.5MHz with 5MHz bandwidth for a third-generation mobile communications system. This filter was fabricated using double-sided YBCO films on a 2inch diameter, 0.5mm thick MgO substrate. In the measurement, it showed good matching in the passband, with reflection better than -15dB. Moreover, the group delay variation is less than 50ns over 89% of the filter bandwidth.
