Determination of Transmission Zeros of Self-Equalized Cross-Coupled Resonator Bandpass Filters

A method to determine the filter order and the locations of transmission zeros of self-equalized bandpass filters is presented, according to given filter specifications by optimization. The objective error function for the optimization is computed from...

In many RF/microwave communications systems, a bandpass filter with a flat group delay is demanded, in addition to its selectivity. One way to obtain this is by designing a self-equalized filter, in which the group delay equalizer is realized within the filter itself. In general, for a self-equalized filter,...
