The Advantech Wireless Technologies Low Noise Block Converter (LNB) ALNB-CT™ is a low noise, highly dynamic range amplifier suitable for use in Tropo receiver applications where ultra-low noise and high reliability are critical, as well as in other systems operating in the frequency range of 4.4 to 5.0 GHz.

These LNBs are addressing a new generation of Tropo Scattering systems, designed to operate in L-band instead of the traditional 70 MHz IF band. This translates in an overall system cost reduction, by removing the need for separate frequency converters.

The Advantech Wireless TROPO LNBs provide an industry leading MTBF of over 200,000 hours.


  • Input Isolator
  • Redundant operation
