How much power is being absorbed by the load when a directional power meter connected between a transmitter and a terminating load reads 100 watts forward power and 25 watts reflected power?

  1. 100 watts
  2. 125 watts
  3. 112.5 watts
  4. 75 wattsRespuesta correcta

Explicación

Power actually dissipated in the load is the forward power minus the power that comes back, so 100 watts forward less 25 watts reflected leaves 75 watts absorbed. The forward reading alone overstates the delivered power because it includes energy that returns to the transmitter.
