SAT-FE-12212-S1

Rev. 1.0

Description:
Model SAT-FE-12212-S1 is a full band, WR-12 orthomodetransducer (OMT) that operates between 60 and 90 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 OMTshows high port isolation while providing a low insertion loss.
The OMT is configured with a 0.122” x 0.122” squarewaveguide for the antenna port and two WR-12 waveguides for the horizontal and vertical ports. Allports have standard UG-387/U anti-cocking flanges and 4-40 threaded holes.
