Modular Design of Waveguide Bandpass Filters With Improved Stopband and High Selectivity

open access: yesIEEE Journal of Microwaves, 2023
A class of waveguide bandpass filters (BPFs) with parallel coupling topology is proposed by stacking rectangular cavities. Compared with transversal filters, each layer comprises more than one cavity, and these cavities are cascaded with electric or ...

Multi‐band glass‐integrated bandpass filters for new radio (NR) communications

open access: yesElectronics Letters, 2023
A class of multi‐band bandpass filters (BPFs) based on glass‐integrated multi‐resonant cells (MRCs) are reported. Each MRC comprises multiple in‐parallel connected series‐type resonators that create passbands in‐between transmission zeros (TZs)—located ...

Plant identification via adaptive combination of transversal filters [PDF]

open access: yes, 2006
For least mean-square (LMS) algorithm applications, it is important to improve the speed of convergence vs the residual error trade-off imposed by the selection of a certain value for the step size.

Transversal directional filters for channel combining [PDF]

open access: yes, 2013
A new concept for the design of power combiners based on matched directional filters is presented. The directional filters consist of individual balanced sections composed of hybrids and single resonators. Each of the sections corresponds to a pole of an
