# 333-346 NUMERICAL SYNTHESIS DESIGN OF COUPLED RESONATOR FILTERS By S

The technique is then used to synthesize and design fil-ters with full or almost full coupling matrices by selecting, among the infinite number of solutions, the matrix that corresponds to the actual implementation.

### Numerical synthesis design of coupled resonator filters.

A conventional bandpass filter works under single dominant resonant modes of a few cascaded transmission line resonators and its operating bandwidth is widened via enhanced coupling between the adjacent resonators.
