SAH-5037531060-165-S1-148-DP

Rev 1.1

Description:
SAH-5037531060-165-S1-148-DP is a dual
polarized, WR-15 choke flange feed hornantenna assembly that operates from 50 to75 GHz. The assembly features an integrated
orthomode transducer (OMT) that provides
high port isolation and a broad band scalarhorn that provides low sidelobe levels. TheOMT enables the antenna to separate acircular 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 40 dB typicalisolation 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 andvertical ports are WR-15 waveguides with UG-385/U anti-cocking flanges. Coaxial port configurations arealso available under different model numbers. The orthomode transducer (Model SAT-FV-14815-S1),
compact square to circular transition (Model SWT-148165-SB-C-QC), and choke flange feed hornantenna (Model SAH-5037531060-165-S1) can be purchased separately.
