We are aware in this rapidly changing market that you need answers quickly, that is why we answer every phone call and assist you in the selecting of a part number and type of filter topology that will meet your needs.

Planar Filter Company has in place a quality control system that ensures a reliable product from one piece to a production run. Before releasing any new design for prototyping, we use state of the art filter synthesis and computer simulation on every filter to meet and exceed your requirement. Once the computer-aided design is finished we have the latest test equipment to ensure that every product meets your specifications.
