Q. Behavior of a transistor in power amplifiers is unpredictable at all input signal levels.

  • (A) true
  • (B) false
  • (C) ---
  • (D) ---

✅ Correct Answer: (B) false
Explanation: a transistor behaves linearly for signal powers below 1db compression point and so, the small –signal scattering parameters should not depend either on the input power level or the output termination impedance.
