This selective super low noise preamplifier uses the latest PHEMT transistor technology from Agilent. Due to his high technical performance - low noise figure, high gain and very high IP3 - it is the ideal preamplifier for contest operation as well as EME, Meteorscatter, Aurora and tropo DX.
  • Low noise figure and high gain
  • LC filter (144 MHz) for good selectivity
  • Milled aluminium case
  • High IP3, ideal for contest operation
  • Unconditionally stable. No parasitic oscillations in case of poor antenna match
  • EME (Earth - Moon - Earth)
  • Contest operation
  • Meteorscatter
  • Aurora
  • Tropo DX
  • Amplifier does not contain a coaxial relay!
  • Maximum input power 1 mW
