Ferro manufactures dielectric materials for a wide variety of high-frequency applications, including resonators, filters and antennas. This table presents material properties of some of the materials available for these applications. The data represents a puck of material in a microwave cavity test fixture with no metalization and, consequently, describes the performance of the dielectric material only.
