SAQ-333039-315-S1

Rev 1.1

Description:
Model SAQ-333039-315-S1 is a Ka-band spot-focusing lensantenna that delivers a typical peak to first null spot size of1.2” at the focal length of 3.94” (10 cm), and a typical returnloss of 15 dB across the full WR-28 waveguide operating
bandwidth. The antenna is equipped with a Ø0.315” circular
waveguide and UG-599/U-M flange as its antenna port. It
supports both linear and circular polarized waveforms. A
configuration with standard WR-28 waveguide as the antenna
port is offered under model SAQ-333039-28-S1, which only supports linear polarized waveforms, butoffers a convenient equipment interface. The mode transition to convert the antenna port to WR-28
can be purchased separately under model SWT-28315-SB.
