Fast Design of Cross-coupled Filter Substructures

Demostration of how three-dimensional electromagnetic analysis can speed up the realization process of cascaded tri-section bandpass filters
Application Note Fast Design of Cross-coupled Filter Substructures Cross-coupled narrow bandpass filters with asymmetric transmission zeros can be realized in cascaded tri-section topology.1,2,3 Each tri-section creates a single transmission zero below or above the passband. The realization of resonator tri-sections is relatively difficult due to the interaction between the...
