A power added efficiency optimizer apparatus is provided for measuring and monitoring input and output power of an amplifying device, and adjusting the load impedance seen by the amplifying device so that power added efficiency is maintained at optimum levels. A power added efficiency optimizing device includes a variable load impedance that can be controlled, at least one power detection device located after the load, a difference forming apparatus, and at least one coupling device. The power added efficiency optimizing device provides an ability to maintain an amplifier at peak efficiency in a dynamic way and in the presence of changing electromagnetic load conditions.
