An orthomode transducer with a circular waveguide input and two rectangular waveguide outputs is described. The design utilizes a reduced height turnstile and two identical reduced height E-plane power combiners. A Ku band version of this device has been constructed and tested. The inputs and outputs return losses were less than -30dB, the isolation between the two rectangular outputs is > 60dB and the transmission loss was 0.1dB. Moreover a yield analysis has been done for various tolerances assuring a precision of 0.05mm ± that indicate a high stability of the possible errors of the values of the designing variables.
