Q

What effect does excessive coupling between the output circuit of an oscillator and an antenna have?

🔍 Key Concepts

• Oscillator coupling between output circuit and antenna • How excessive loading affects frequency stability of an RF oscillator • Difference between instability of frequency vs. distortion or modulation of the signal

💭 Think About

• Think about what happens to an oscillator if the antenna draws too much energy from the tank circuit—does this primarily change the frequency, the modulation, or both? • Which option best describes a general loss of stable operation of the oscillator itself, rather than a specific distortion effect? • Is the question asking about instability of a specific component (like an op-amp) or of the RF oscillator circuit as a whole?

✅ Before You Answer

• Identify which choices describe general oscillator instability versus very specific or less likely side effects • Ask whether op-amps are necessarily involved in a typical RF oscillator–antenna coupling question • Consider that excessive coupling usually means excessive loading, and recall the primary symptom of an over‑loaded oscillator.
