TW4320/TW4322

The TW4320/TW4322 is a wideband GNSS antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1575 to 1606 MHz). It features a small patch element with 40% wider bandwidth than previously available in this format.

Features

  • 40% wider bandwidth
  • High rejection SAW filter
  • Low noise LNA: 1dB
  • Temperature compensating LNAs

Benefits

  • Great out-of-band signal rejection
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
    temperatures

A tight pre-filter is included in the TW4322 to protect against saturation by high level sub-harmonics and L-Band signals.

The TW4320/TW4322 are housed in a compact, magnetic mount, IP67 compliant housings. It is RoHS and REACH compliant.

For further details, please download the Datasheet.

Mechanical:

Architecture: Wideband single feed patch
Size: 38mm x 38mm dia. x 14.3mm H
Weight: 50g
Enclosure: Radome and Base: ASA Plastic
Attachment Method: Magnetic
Environmental: IP67, REACH, and RoHS compliant

Electrical:

LNA Gain: 28 dB
Supply Current: 10mA typ. 12mA max. @ 85°C
Supply Voltage: 2.5 to 16 VDC nominal (12VDC recommended max.)
Noise: 1 dB typ.(TW4320); 3.5 dB typ. (TW4322)
Axial Ratio (over full bandwidth): 6 dB typ., 8 dB max.

For further details, please download the Datasheet.

The attached document (PDF) contains graphical representation of the axial ratios, Phase Center Variation (PCV), Phase Center Offset (PCO), and gain patterns over elevation and rotation (azimuth) as measured by an independent laboratory.
