Low-noise microwave amplifier with limiter ELU-Z-35

   This amplifier (module) is a functionally complete unit providing input signal amplification and stabilization of the output signal level in the operating temperature range (- 50 0C … + 65 0C) and is designed for use in input circuits of radar receivers.

   The amplifier is equipped with a limiter limiting high-power input pulse signal to a level which is safe for module operation, it has a control input allowing to check its condition and a protection against high supply voltage up to 30 V and application of the supply voltage in reverse polarity up to minus 18 V as well as against pulse surges in module power supply circuit.
