Designed for use in the receiving units of modern weather and navigation radars and provides:

  • reception in a wide frequency range and conversion of radar signals in modes with a narrow and wide band of IF output signals;

  • discrete adjustment of the transmission coefficient by external control signals in broadband mode;

  • high radio-tightness of the receiver due to shielding of all high-frequency modules.

 

The radar receiving module has an input attenuator for adjusting the input signal level and protecting the low-noise amplifier for the duration of the probe pulse, with a short recovery time.
