SAT-FW-10010-S1

Rev. 1.3

Description
Model SAT-FW-10010-S1 is a WR-10 orthomodetransducer (OMT) that operates between 75 and110 GHz. The OMT separates a circular or ellipticalpolarized 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 whileproviding a low insertion loss. The OMT is configured with a 0.100” x 0.100” square waveguide for theantenna port and two WR-10 waveguides for the horizontal and vertical ports. All ports have standard
UG-387/U-M anti-cocking flanges.
