SAF-7738731725-110-S1

Rev. 1.1

Description:
Model SAF-7738731725-110-S1 is an E-band scalar feedhorn antenna that operates from 77 to 87 GHz. The
antenna offers 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 0.110” diametercircular waveguide that supports both linear and circularpolarization. A rectangular waveguide port configuration that only supports linear polarization isavailable under a different model number.
