SAT-FG-05105-S1 is a WR-05 orthomode transducer (OMT) that operates between 140 and 220 GHz. The OMT separates a circular or elliptical polarized waveform into two linear, orthogonal waveforms or combines two linear polarized waveforms into one circular or elliptical polarized waveform or vice versa. The OMT also supports either vertical or horizontal polarized waveguide forms. The OMT shows high port isolation while providing a low insertion loss. The OMT is configured with a 0.051” x 0.051” square waveguide for the antenna port and two WR-05 waveguides for the horizontal and vertical ports. All ports have UG-387/U-M anti-cocking flanges.
