SAF-1141741725-082-S1

Final Rev 1.0Description:
Model SAF-1141741725-082-S1 is a D-band scalar
feed horn antenna that operates from 110 to 170 GHz.
The antenna offers a 17 dBi nominal gain, 25 degree
typical half power beamwidth, and -25 dB typical side
lobe level. The scalar feed horn is equipped with a0.082” diameter circular waveguide that supports
both linear and circular polarization. A rectangular waveguide port configuration that only supports
linear polarization is available under a different model number.
