The bandwidth of an RF tuned amplifier is dependent on____________?
Correct answer: A. Q -factor of the tuned o/p circuit
- A. Q -factor of the tuned o/p circuit
- B. Q -factor of the tuned i/p circuit
- C. Quiescent operating point
- D. Q-factor of the o/p and i/p circuits as well as quiescent operating point
Explanation
For the usual RF tuned amplifier, bandwidth is inversely proportional to the Q-factor of its tuned output circuit, approximately BW = f₀/Q. A higher Q therefore produces a narrower bandwidth.
