SAF-1442241725-067-S1

Rev 1.0

Description:
Model SAF-1442241725-067-S1 is a G-band
scalar feed horn antenna that operates from 140
to 220 GHz. The antenna offers a 17 dBi nominal
gain, 25 degree typical half power beamwidth,and -25 dB typical side lobe level. The scalar feedhorn is equipped with a Ø 0.067” circular
waveguide that supports both linear and circularpolarization. A rectangular waveguide port configuration that only supports linear polarization isavailable under a different model number.
