Reactel Cavity Filters are designed to meet the most stringent requirements with low loss and high selectivity. Depending on the frequency and loss specifications, these units can be manufactured in sizes as small as 0.25″ wide and as large as 2.5″ wide, covering a frequency range from 30 MHz to 50 GHz. Reactel’s C7 series is the most versatile of the cavity filter family. They are machined from solid aluminum bar stock and silver plated to keep losses at a minimum. All units can be designed with 2 to 16 sections, depending on your requirements. By using resonant modes, and quarter wave or helical resonators we are able to produce filters with 3 dB bandwidths from 0.5 to 10% wide. All of Reactel, Incorporated’s cavity filters are designed using the latest in CAD/CAM equipment and machinery. This approach assures that accuracy and repeatability will be maintained throughout the manufacturing process regardless of quantity ordered, and also allows us to offer you the most cost competitive pricing available.
