🔍 Key Concepts

• Parasitic oscillations in RF/power amplifiers • How neutralization works to cancel unintended feedback • Difference between tuning for power/SWR vs fixing instability

💭 Think About

• Ask yourself: Which option deals directly with stopping unwanted self‑oscillation inside an amplifier, not just improving output or matching the load? • Which choice involves canceling or controlling feedback between input and output stages? • Which options are about adjusting the antenna/load match rather than the internal behavior of the amplifier?

✅ Before You Answer

• Identify which choices are about load matching (SWR, output tuning) versus internal circuit stability. • Recall that parasitic oscillations are usually caused by unintended feedback or coupling inside the amplifier. • Verify which method is specifically used to cancel unwanted feedback between stages of an RF power amplifier.
