Miniature Cryo-LNA - Ka-Band

The LNA is intended for use on K band SATCOM antennas operating around 20 GHz for reception. The LNA has two operating modes; "normal" and "turbo". The difference between the two modes is the noise figure performance.

In "turbo" mode the noise figure is significantly improved (by a factor of 3) compared to "normal" mode by cooling the LNA circuit. The intended application of this LNA is for critical data communications, when it is necessary to boost the performance of the receiving system for certain periods of times.

Key Features:
  • Boost the noise figure in "Turbo" mode down to 0.5dB
  • Mitigate communication degradation as rain
  • "Normal" mode = Ambient operation
  • Satcom applications military and civil
  • Satcom on the Move (SOTM)
  • No servicing due to low operating duty cycle
  • Robust cooler used in military equipment
  • Adaptable to other frequency bands
