CMI has developed a range of Polarizers from 3 to 200 GHz to provide a constant 90 or 180 degrees phase shift between two orthogonal linear components. Each polarizer is precisely designed for optimum performance, size, and manufacturability. By combining precision CAD tools, design techniques, and precise fabrication, CMI can produce these high performance devices with no tuning screws.

This leads to improved power handling, very low PIM, and the elimination of bench tuning. Depending on the application, these Polarizers can be manufactured by direct machining/EDM or by copper electroforming in a single piece construction with integral flanges for high mechanical strength and very low PIM.
