The amplifier has been designed for professional cable and MATV systems with return channel. This house/building amplifier is equipped with output stage using Gal-As semiconductor components, working in push-pull mode. The next innovation is driving stage, employing IC made of Si-Ge semiconductor. Such a solution significantly reduces non-linear distortions, especially of second order.
It enables signal level equalization in forward and return path.
Main features
  • push-pull output stage made of Gal-As semiconductor components
  • attenuator and cable attenuation equalizer (forward path)
  • equalizer between the 1st and 2nd stage of forward path
  • selectable active/passive return path
  • attenuator at the input of return path
  • equalizer at the output of return path
  • attenuator and equalizer at the output of return path
  • test connector (input, -20dB)
  • test connector (output, -20dB)
