      產品詳細介紹Product Introduction

      TW141 40dB Inline RF Amplifier (Full GNSS)


      The TW141 is a rugged, waterproof wideband 40 dB gain in-line amplifier, specially designed to boost weak frequency signals from 1100 to 1700 MHz, including L-Band and all GNSS (GPS, GLONASS, BeiDou, and Galileo) signals.

      The TW141 provides for much longer cable runs from antenna to receiver without degradation of system sensitivity, for applications such as mast-mount, large vehicle and timing systems.

      The TW141 passes DC directly from input to output to support centre conductor DC supply to the antenna, and so avoids the need for an additional bias source or bias “T”.

      It is enclosed in a robust weatherproof cylindrical nickel-plated brass housing (IP67-compliant) and is available with SMA and TNC female connectors.

      Amplifiers are directional and must be installed in the orientation indicated on the product label (arrow points away from antenna).        
       
      Applications:
      •  Commercial and Military L-Band Satellite Systems
      • Wireless Telecom & Cellular Base Station Timing Applications
      • GNSS (GPS, GLONASS, Galileo), SBAS and Telematics Systems
      • Commercial and Industrial Timing and Synchronization Applications
