TW3320/TW3322 严格任务、性价比高天线

The TW3320/TW3322 is a high performance antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1575 to 1606 MHz). It features a patch element with 40% wider bandwidth than hitherto available in this format. Unlike its competitors, both GPS-L1 and GLONASS signals are included in the 1dB received power bandwidth.

Applications

 Cost Sensitive Mission Critical Positioning 价格敏感严格任务定位

 Military & Security 军用与保安

 Fleet Management & Asset Tracking 车队管理与资产管理

  • 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

The TW3322 has an additional tight pre- filter to protect against saturation by high level sub-harmonics and L-Band signals. 预滤波

The TW3320/TW3322 are housed in a through-hole mount, weather-proof enclosure for permanent installations. They are available with either a flat or conical radome in either grey or white. The TW3320/TW3322 is also available with either a TNC or N-Type connector on the base of the antenna or with a flying lead and a variety of connectors.   TNC、N-Type连接器等可选。

L-Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. They are IP67, RoHS, and REACH compliant. 非屋顶有L型支架、管型支架可选。
