SAL-2632732410-28-C1

Rev. 1.1

Description:
Model SAL-2632732410-28-C1 is a Ka-band circular polarized
lens corrected antenna that operates from 26.3 to 27.2 GHz.
At center frequency, the antenna delivers 24 dBi nominal gain
and a 10 degree half power beam width. The antenna
employs a low loss lens to offer excellent aperture efficiency
and low sidelobe levels. The antenna incorporates a linear tocircular waveform polarizer. This feature allows either RHCP
or LHCP operations, depending on how the port is selected.
This antenna is equipped with a WR-28 waveguide and UG599/U flange as its input port.
