Rev 1.2

Description:
SAH-2434231060-328-S1-280-DP is a dual polarized, WR-28
choke flange feed horn antenna assembly that covers
several popular 5G bands in the frequency range of 24 to 42
GHz. The antenna features an integrated orthomodetransducer (OMT) that provides high port isolation and abroad 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 polarizedwaveguide forms. At center frequency, the horn antenna exhibits 10 dBi nominal gain and a typical half
power beamwidth of 60 degrees and -25 dB sidelobe level for E plane and -35 dB for H Plane. Theantenna exhibits 35 dB typical port isolation between the horizontal and vertical ports. The horizontaland vertical ports are WR-28 waveguides with UG-599/U flanges and 4-40 threaded holes.
