The superior power density and power efficiency of GaN-based amplifiers make them ideal for the manufacturing of smaller and more efficient transmitters. There’s only one issue: the non-linear behavior on maximum power areas can degrade the transmitted signal to a point where it becomes useless.
Adjacent Channel Power Ratio (ACPR) measurements can help. Learn more about using this method to establish amplifier behavior under a specific modulated input signal to achieve a clear indication of amplifier performance for a given application.
