Which outcome results when avalanche breakdown occurs at a semiconductor junction in an RF power amplifier?

A)Signal distortion and harmonic generation
B)Increased carrier mobility in active region
C)Improved amplifier power efficiency
D)Reduced thermal noise floor margin

💡 Explanation

Signal distortion causes harmonic generation. Avalanche breakdown generates excessive carriers exceeding the dopant profile via Impact Ionization, therefore, signals become non-linear rather than remaining clean due to device saturation under high voltage conditions which cause distortion.
