Abstract
An asymmetric, broadband, compact and low-PIM orthomode transducer comprised of two parts is presented. Mating of the two parts results in the formation of a choke flange as well as a critical impedance step which suppresses unwanted modes and enables broadband matching of the junction between the two parts. Furthermore, a cruciform-quatrefoil waveguide type is utilized that transitions to an aperture. This waveguide configuration can lead to a lower overall part length, an improved reflection, and reduced manufacturing costs.
