← TechnologyWhich outcome occurs when a resonant circuit in a Class-E power amplifier is poorly tuned.?
A)Reduced harmonic suppression in the output✓
B)Increased power supply ripple voltage
C)Decreased switching transistor voltage stress
D)Enhanced amplification of unwanted signals
💡 Explanation
When a resonant circuit is poorly tuned, the impedance at harmonic frequencies drops off less sharply because the resonance is broadened, leading to increased harmonic content. Therefore, reduced harmonic suppression results, rather than increased ripple, decreased transistor stress, or enhanced amplification requiring different resonant properties.
