SAL-2232732212-42-S1

Rev. 1.2

Description:
Model SAL-2232732212-42-S1 is a K-band lens corrected
antenna that operates from 22 to 26.5 GHz. At center
frequency, the antenna delivers 22 dBi nominal gain and
12 degrees typical half power beamwidth. The antenna
employs a low loss lens to offer excellent aperture
efficiency and low sidelobe levels. The lens corrected
antenna is equipped with a WR-42 waveguide and UG595/U flange as its input port. It supports linear polarized
waveforms.
