SAF-1141741535-082-S1

D Band Scalar Feed Horn Antenna, 15 dBi Gain
SAF-1141741535-082-S1 is a D-band scalar feed horn antenna that
operates from 110 to 170 GHz. The antenna offers a 15 dBi nominal
gain, 35 degree typical half power beamwidth, and -25 dB typical side
lobe level. The scalar feed horn is equipped with a 0.082” diametercircular 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.
