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.

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.
