Orthomode Transducers (OMT)

Anteral designs and manufactures compact orthomode transducers (OMTs) for communication and radar systems. Depending on the client requirements, we offer the best optimized design in terms of complexity and price. Anteral has developed multiple designs of OMTs up to 160 GHz, but higher frequencies can be requested. Moreover, the phase difference between the orthogonal polarizations can be reduce to the minimum, thus enabling applications where phase matched outputs are required.

This kind of components are used for either combine or separate two orthogonal linear polarized signals. The OMTs support either horizontal or vertical polarized signals with more than 35 dB cross-polarization rejections and 35 dB isolation. Both full waveguide band models and narrow band models with enhanced cross polarization and isolation can be requested.
