WR-10 Dual-Polarized Choke Flange Feed Horn Antenna

SAH-7531141060-110-S1-100-DP is a dual polarized, WR-10 choke flange feed horn antenna assembly that operates from 75 to 110 GHz. The assembly features an integrated orthomode transducer (OMT) that provides high port isolation and cross-polarization cancellation and a broad band scalar horn that provides low sidelobe levels. The OMT enables the antenna to separate a circular or elliptical polarized waveform into two linear, orthogonal waveforms or vice versa. The dual polarized horn also supports either vertical or horizontal polarized waveguide forms with 35 dB typical cross polarization rejection and 40 dB typical isolation between the V and H ports. At center frequency, the horn antenna exhibits 10 dBi nominal gain, typical half power beamwidth of 60 degrees and typical sidelobe levels of -30 dB. The horizontal and vertical ports are WR-10 waveguides with UG-387/U-M anti-cocking flanges. Coaxial port configurations are also available under different model numbers. The orthomode transducer (Model SAT-FW-10010-S1), compact square to circular transition (Model SWT-100110-SB-C-QC), and choke flange feed horn antenna (Model SAH-7531141060-110-S1) can be purchased separately.
