IMPATT Diode : Definition, Construction, Equivalent Circuit, Operation and Applications

on

IMPATT Diode:

  • IMPact ionization Avalanche Transit-Time diode: It is a form of high-power semiconductor diode used in high-frequency microwave devices. 
  • IMPATT diode operates in reverse bias. It exhibits a negative resistance region due to the impact of avalanche and transit time effects. 
  • They have negative resistance and are used as oscillators and amplifiers at microwave frequencies.
