HIGH-VOLTAGE UNIPOLAR PULSE AMPLITUDE LIMITER Russian patent published in 2012 - IPC H03G3/30 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering and specifically to radar, and can be used in excitation systems of avalanche diode or Gunn diode microwave oscillators. The unipolar pulse amplitude limiter has: an input and an output, a bipolar transistor whose emitter is connected to the output of the limiter and the collector is connected to a conductor which is common for the whole device, a first resistor whose first lead is connected to the emitter of the bipolar transistor and the second lead is connected to the input of the limiter, a second resistor whose first lead is connected to the emitter of the bipolar transistor and the second lead is connected to the conductor which is common for the whole device, a third resistor whose first lead is connected to a power supply, a stabilitron whose cathode is connected to the second lead of the third resistor and the anode is connected to the conductor which is common for the whole device, and a capacitor whose first lead is connected to the second lead of the third resistor and the second lead is connected to the conductor which is common for the whole device; there is semiconductor diode whose anode is connected to the base of the bipolar transistor and the cathode is connected to the second lead of the third resistor.

EFFECT: possibility of obtaining pulses whose amplitude is many times greater than the maximum allowable base-emitter voltage of modern bipolar transistors.
