  Septum Polarizers

CMI's Septum Polarizers have circular common ports and rectangular waveguide ports which support both left- and right- hand circular polarization.

Septum polarizers can be fabricated by either direct machining in split-block construction or by copper electroforming. 

Our Septum Polarizers find typical applications in Radiometers and Dual Polarization Feeds. These products offer high isolation with low insertion loss, and excellent temperature stability.

We are happy to help design a custom septum polarizer for the customer whose needs exceed the performance of our standard products.
