Abstract

© 2016 IEEE. This letter presents a novel circuital extraction possibility for filter prototypes including resonant and non-resonant nodes (NRNs). The proposed technique involves the extraction of a cross-inverter evaluated at infinity and a dangling resonator connected to an NRN at the same time. Therefore, two transmission zeros are extracted in one iteration step. This is an extension upon the results of the outstanding and original synthesis of cross-coupled filters proposed by S. Tamiazzo and G. Machiarella, providing different sets of configurations not considered by their methodology but within the same family of topologies. An example is shown in order to illustrate the proposed technique.
