← TechnologyWhich outcome occurs when reverse bias exceeds avalanche breakdown voltage in a tuned IMPATT diode?
A)Radio frequency energy generation✓
B)Gradual reduction in capacitance
C)Significant increase in thermal runaway
D)Stable and linear current amplification
💡 Explanation
Radio frequency energy generation occurs due to impact ionization avalanche transit-time (IMPATT) effect. Because reverse breakdown triggers the sustained high-frequency oscillations. Therefore, RF energy is generated rather than linear amplification, occurring during forward active mode.
