TW4320/TW4322 紧凑型天线、价廉物美

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.
