Fairview Microwave's Power Added Efficiency Calculator will return efficiency on an amplifier from input, output, and DC power.
The Power Added Efficiency of an amplifier is the ratio of produced signal power (difference between input and output power) and the DC input power for the amplifier.
**Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
