RF Orthomode Transducers OMT
Orthomode Transducers separate a signal applied to the circular waveguide input port into its two linear orthogonal components at the rectangular waveguide output ports with greater than 30 dB isolation between the polarizations. In reverse, two orthogonal linearly polarized signals combine, producing an output in the circular waveguide port. The resulting polarization may be linear, circular, or elliptical depending on the relative phase and amplitude of the two orthogonal input signals.
Note: Our website contains just a few types of Orthomode Transducers we build. Consult with us for your specific needs.
