SAL-3333732905-250-S1

Rev. 1.1

Description:
Model SAL-3333732905-250-S1 is a Ka-band lens corrected
antenna that operates from 33 to 37 GHz. At a center
frequency of 35 GHz, the antenna delivers 29 dBi nominal gain
and 5 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 isequipped with a 0.250” diameter circular waveguide and UG599/U-M flange as its input port. It supports both linear andcircular polarized waveforms.
