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.
PINCH OFF VOLTAGE – pinch off voltage in jfet
Formula
PAE = ((RFout – RFin) / RFDC) × 100
CMOS PMOS NMOS (nmos pmos and cmos)
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
IS THERE ANY DIFFERENCE BETWEEN PHOTODIODE AND…
Result: PAE = ((5 – 1) / 10) × 100 = 40%
Who uses it
Useful for RF engineers and designers evaluating amplifier efficiency in communication and radar systems.
