Q. If a power amplifier has an output power of 10 W, and an amplifier gain of 16.4 dB, then the input drive power is:

  • (A) 400 mw
  • (B) 225 mw
  • (C) 229 mw
  • (D) 240 mw
💬 Discuss
✅ Correct Answer: (C) 229 mw
Explanation: input drive power required to get an output of 10 w is pout (dbm)- g (db). g is the gain of the amplifier. substituting the given values in the above equation, 229 mw.
