Amplifier & Receiver
Power Added Efficiency (PAE) Calculator
Work out an amplifier's power added efficiency from its RF input, RF output and DC supply power.

Enter the inputs above and select Calculate.
Formula: PAE = (P_out − P_in) / P_DC × 100%
Drain efficiency ignores the drive power: η = P_out / P_DC. The gap between the two widens as gain falls.
Dissipated power is what the heatsink has to carry: P_DC + P_in − P_out.
