SAT-FX-90090-S1

Rev. 1.0

Description
Model SAT-FX-90090-S1 is a full band, WR-90 orthomodetransducer (OMT) that operates between 8.2 and 12.4 GHz. The
OMT separates a circular or elliptical polarized waveform into twolinear, orthogonal waveforms or combines two linear polarized
waveforms into one circular or elliptical polarized waveform. The
OMT shows high port isolation and high cross-polarization whileproviding a low insertion loss. The OMT is configured with a 0.900”
x 0.900” square waveguide for the antenna port and two WR-90
waveguides for the horizontal and vertical ports. All ports have standard UG-39/U flanges.
