سؤال 269

What can be added to the output of a transceiver to increase the transmitted output power?

  1. A potentiometer
  2. An RF power amplifierپاسخ درست
  3. An impedance multiplier
  4. All these choices are correct

توضیح

Only an RF power amplifier actually adds power, taking the transceiver's output as drive and delivering a higher-level signal to the antenna. An adjustable resistive control only divides or controls voltage, and there is no such thing as an impedance multiplier that raises transmit power, so the all-of-these choice fails.
