  • Extremely low noise figure
  • Remote power supply via output connector possible
  • Low-power enable input pin
  • Reverse polarity protection


The KU LNA 750850 A WG is KUHNE’s newest X-band super low-noise amplifier and was particularly developed for low-noise receive applications, e.g., satellite ground station equipment. Thanks to the combination of an extremely low noise figure, a high gain and high P1dB and IP3, very weak input signals can be amplified with low noise to a power level that is easy to process. The RF input using a WR112 waveguide promises low-loss coupling to the antenna system.

The KU LNA 750850 A WG has a bandwidth of 7.5 GHz to 8.5 GHz and is therefore suitable for a variety of applications in the X-band microwave range, e.g., for the amplification of weak satellite signals in low-noise receivers. Moreover, the KU LNA 750850 A WG shows a gain of typically 65 dB and a very low noise figure of typ. in between 0.7 dB and 0.8 dB. A low power enable pin and reverse polarity protection furthermore increase user friendliness.
