SAY-3334035006-250-S1

Rev 1.1

Description:
Model SAY-3334035006-250-S1 is a Cassegrain antenna thatoffers a nominal gain of 50 dBi and a half power beamwidth of
0.6 degrees across the frequency range of 33 to 40 GHz. The
main reflector is fabricated with fiber glass to offer a lightweight and rugged mechanical structure. The corrugated horn
is used to provide the best feed efficiency and the most uniform
illumination. The input port is a 0.250” diameter circular
waveguide with a UG-599/U flange. The antenna can support
both linear and circular polarized waveforms and is designed
and manufactured for indoor applications. By adding a modetransition, SAGE Millimeter model SWT-28250-SB, the input
port becomes a standard WR-28 waveguide that can only support linear polarized waveforms.
