Function and the main characteristics:
      Ku LNA is intended for operation with the receiving signal of Ku-band satellite communication station.
Main characteristics of Ku LNA:
      - operating frequencies range 12,25…12,75 GHz;
      - noise ratio: no more than 1,1 dB;
      - amplifying ratio in normal ambient conditions not less than 50 dB;
Characteristics of the amplitude-frequency irregularity:
      - no more than 2 dB in the whole operating frequency range;
      - no more than 0,5 at any 40 MHz band of operating frequency range.
Transfer ratio instability at a constant level of the input signal:
      - no more than ±1 dB in operating temperatures range.
Output signal capacity level during compression at 1 dB not less than +10 dBm:
      - input standing-wave ratio: no more than 1,2;
      - output standing-wave ratio: no more than 1,2.
