Patents by Inventor Daniele MARRELLI

Daniele MARRELLI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Rotary radio frequency switches
    Patent number: 11990663
    Abstract: Radio frequency (RF) switches are provided. An RF switch includes a first RF transmission line and a second RF transmission line that are capacitively coupled to each other. Moreover, the RF switch includes a third RF transmission line having a signal trace that is electrically isolated from the first and second RF transmission lines. Related methods of operating filter devices are also provided.
    Type: Grant
    Filed: January 25, 2022
    Date of Patent: May 21, 2024
    Assignee: CommScope Italy S.R.L.
    Inventors: Alessandro Sartorio, Daniele Marrelli, Giuseppe Resnati, Roman Tkadlec
  • Wide bandwidth folded metallized dielectric waveguide filters
    Patent number: 11936086
    Abstract: A metallized dielectric waveguide filter includes an upper metallized dielectric waveguide having a plurality of upper resonant cavities, the upper metallized dielectric waveguide comprising an upper dielectric block having metallized outer walls, and a lower metallized dielectric waveguide having a plurality of lower resonant cavities, the lower metallized dielectric waveguide comprising a lower dielectric block having metallized outer walls. A first of the upper resonant cavities is operatively connected to a first of the lower resonant cavities via at least one coupling window. A first slot having metallized walls is provided in a portion of the upper dielectric block that is part of the first of the upper resonant cavities.
