This calculator determines the power added efficiency (PAE) of an RF amplifier. PAE indicates the amplifier’s ability to convert direct current (DC) input power to useful RF output power, while accounting for internal losses.
Formula
PAE = ((RF out − RF in ) / RF DC ) × 100
Explanation of the formula
The formula calculates the percentage of RF power added relative to the DC power consumed. RF in and RF out are the input and output powers in watts, while RF DC represents the electrical power supplied to the amplifier. A higher PAE value translates to a more efficient amplifier with less thermal losses.
Uses of the calculator
- Evaluate the energy performance of an RF amplifier.
- Compare different amplifiers in terms of efficiency.
- Optimize amplifier design to reduce power consumption.
- Practical tool for RF engineers, technicians and microwave circuit designers.
