KU LNA 200250 A-SMA, Super Low Noise Pre-Amplifier

2000 … 2500 MHz

Analog & digital transmission systems     Satelite ground station     Communication systems

 

  • Extremely low noise figure
  • Remote power supply via output connector possible
  • Low-gain mode via solder pin
  • Reverse polarity protection

The super low-noise pre-amplifier KU LNA 200250 A was particularly developed by Kuhne for S-band receive applications, e.g., satellite ground station equipment. The combination of an extremely low noise figure, high P1dB and IP3, and switchable low-gain mode ensures a very high dynamic range.
