Amplifier

FEATURES AND SPECIFICATION

  • High quality amplification module system at 54/87- 860MHz
  • bandwidth for forward direction and 5-40/65MHz for reverse path.
  • Plug-in duplex filters are capable of two way Transmission;
  • Reverse bandwidth 5-40/ 5-65 optional.
  • Two outputs which can plug-in direction coupler to change output value.
  • Both the input and output have testing points (-20dB).
  • Input, outputs are all equipped with arrestors that
  • reduce mechanical breakdowns from sudden electrical surges.
  • forward, backward power supply allowed.
  • High efficiency transformer / switch power.
  • Modular amplifying and power supply units for easy maintenance.
