SAF-2633331725-315-S1

Rev 1.1

Description:
Model SAF-2633331725-315-S1 is a Ka band scalar feed hornantenna that operates from 26 to 33 GHz. The antennaoffers a 17 dBi nominal gain, 25 degree typical half power
beamwidth, and -28.5 dB typical side lobe level. The scalar
feed horn is equipped with a 0.315” diameter circular
waveguide that supports both linear and circular polarization.
A rectangular waveguide port configuration that only supports linear polarization is available under adifferent model number.
