This calculator determines the Power Added Efficiency (PAE) of an RF amplifier, showing how effectively it converts DC input power into useful RF output power beyond the input signal.
Formula
PAE = ((RFout – RFin) / RFDC) × 100
Formula Explanation
- RFout: Output RF power (W)
- RFin: Input RF power (W)
- RFDC: DC power supplied to the amplifier (W)
Example
Input: RFout = 5 W, RFin = 1 W, RFDC = 10 W
Result: PAE = ((5 – 1) / 10) × 100 = 40%
Who uses it
Useful for RF engineers and designers evaluating amplifier efficiency in communication and radar systems.
