SAT-333-32828-C1

Rev. 1.2

Description:
Model SAT-333-32828-C1 is a WR-28 orthomode transducer (OMT)
that operates between 24 and 42 GHz. The OMT separates acircular 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 a0.328” 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.
