SAT-363-25028-C1

AdvancedDescription
Model SAT-363-25028-C1 is a WR-28 orthomode transducer(OMT) that operates between 30 and 42 GHz. The OMTseparates a circular or elliptical polarized waveform into twolinear, orthogonal waveforms or combines two linear polarized
waveforms into one circular or elliptical polarized waveform orvice versa. The OMT also supports either vertical or horizontal
polarized waveguide forms. The OMT shows high port isolation while providing a low insertion loss. TheOMT is configured with a 0.250” diameter circular waveguide for the antenna port and two WR-28
waveguides for the horizontal and vertical ports. All ports have standard UG-599/U flanges with 4-40
threaded holes.
