Power Added Efficiency Diagram

RF AMP RF Input Pin RF Output Pout DC Input Pdc PAE PAE = (Pout - Pin) / Pdc × 100%

Formulas

PAE (%) = 100 × (Output RF Power - Input RF Power) / DC Input Power
mW to W = mW × 0.001
dBm to W = 10^((dBm - 30) / 10)
dBW to W = 10^(dBW / 10)

Diagrams & Theory

Power added efficiency shows how efficiently an RF amplifier converts DC power into additional RF output power.

It subtracts the input RF power from the output RF power, then compares the added RF power against the DC power consumed.

Example

Input Example

Input RF Power: 10 mW
Output RF Power: 100 mW
DC Input Power: 1 W

Output

Added RF power is 0.09 W and power added efficiency is 9%.
