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.

The KU LNA 200250 A has a bandwidth of 2 GHz to 2.5 GHz and is thus suitable for a variety of applications in the S-band microwave range, in particular for the amplification of weak satellite signals in low-noise receivers. Furthermore, the KU LNA 200250 A is characterized by a very low noise figure of typ. 0.35 dB and a gain of typically 53 dB. By connecting the second solder pin to ground, the gain can be decreased to typ. 35 dB without affecting the noise performance. The reverse polarity protection furthermore increases user-friendliness.
