SAL-2734032220-28-S1-RL

Rev 1.2

Description:
Model SAL-2734032220-28-S1-RL is a Ka-band lens corrected antennathat operates from 26.5 to 40.0 GHz. At a center frequency of 33.25
GHz, the antenna delivers 22 dBi nominal gain, 20.0 degrees typical half
power beamwidth on the E-plane, and 8.0 degrees typical half power
beamwidth on the H-plane. The antenna employs a low loss lens tooffer excellent aperture efficiency and low sidelobe levels. The lenscorrected antenna is equipped with a standard WR-28 waveguide andUG-599/U flange as its input port. It supports linear polarized waveforms.
