SAG-2032532806-396-S1

K-Band Gaussian Optics Antenna, 20 to 24.5 GHz, 6.2°
SAG-2032532806-396-S1 is a 6” K-Band Gaussian antenna that
operates from 20 to 24.5 GHz. The Gaussian antenna delivers a 28 dBi
nominal gain and 6.2 degree half power beamwidth. The antenna
supports both linear and circular polarized waveforms and employs acorrugated feed horn to offer excellent aperture efficiency, high crosspolarization rejections, and low sidelobe levels. This model is equippedwith a 0.396” circular waveguide and UG-595/U flange as its input port.
By adding the mode transition, Eravant model number SWT-42396-SB,
the input port becomes a WR-42 rectangular waveguide, which can only
support linear polarized waveforms.
