Abstract
A maximal-flat-type bandpass filter using two TM/sub 01 delta /-mode dielectric resonators oriented axially in a high-T/sub c/ superconductor cylinder was designed with 3-dB bandwidth of 36 MHz at 11.958 GHz. For this filter an insertion loss below 0.1 dB and a frequency temperature coefficient of -2.7 ppm/K were realized in the range of 20 to 50 K.<>
