At ComNav, quality is a point of pride. Our wide array of typologies (including Helical, Evanescent, Combline, Interdigital, Dielectric Resonator and Waveguide) ensures that exactly the right filter is developed for your application. Our combination of modern materials, CNC machining, Super Q ceramics and temperature-compensated aluminum cavities means that ComNav cavity filters can achieve performance and production yields that are among the best in the industry.
To speed production turn- around, ComNav's cavity filters are "over-designed" at the front end, reducing size, testing cost and eliminating the need for coupling adjustment. Our innovative method of temperature compensation eliminates the need for Invar or multi-part construction - significantly reducing cost and yielding temperature performance of < 5 ppm in aluminum. Resonator count is reduced and unloaded Q is minimally affected, so there's lower loss and group delay variation.
