Down Converter MKU LNC 57


  • Low noise converter for conversion of the 5.7 GHz amateur radio band to the SAT receiver range 1,3...1,8GHz
  • Low noise figure and high gain
  • Use of the most advanced GaAs - HEMT - FET`s
  • In-built bias „T“, for power feed up the coax cable
  • It was possible by using a „Microstrip band pass filter“ for optimum bandselection at 5,7 GHz, as well as Schottky - diode - mixer and DRO resonator to realize high frequency stablility and high dynamics range.
  • Unconditionally stable. No parasitc oscillatiors in case of poor antenna match or by using filter - diplexer at relais radio stations.
