SAF-2334431535-328-S1-280-DP

WR-28 Dual Polarized Scalar Feed Horn Antenna, 23 to44 GHz, 15 dBi Gain

SAF-2334431535-328-S1-280-DP is a broadband WR-28 dual polarized
scalar feed horn antenna that covers several popular 5G bands in thefrequency range of 23 to 44 GHz. The antenna features an integrated
orthomode transducer (OMT) that provides high port isolation and abroad band scalar horn that provides low sidelobe levels. The OMTenables 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 polarizedwaveguide forms. At center frequency, the horn antenna exhibits 15 dBi
nominal gain and a typical half power beamwidth of 35 degrees and -25
dB sidelobe levels, respectively. The antenna exhibits 40 dB typical port
isolation between the horizontal and vertical ports. All ports have UG-599/U
compatible flanges with 4-40 threaded holes. The OMT (SAT-343-28028S1), compact square to circular transition (SWT-280328-SA-C-QC), andbroadband scalar feed horn (SAF-2234431535-328-S1) can all bepurchased separately. Additional customization options, such as converting
the waveguide ports to coaxial ports by adding waveguide to coax adapters(SWC-2434431505-282F-R1 or SWC-2434431505-282M-R1), are available
under different model numbers.
