The next generation of mobile communication (5G) is upon us, and with that newtypes of technologies are needed for improved data rates, reliability, response timeand increased utilization. In this report, two highly efficient linear power amplifiersare characterized and tested with simulated communication signals. The purpose ofthe amplifiers is to be integrated into antenna arrays that will transmit amplifiedcommunication signals to mobile users.One of the amplifiers is tested with modulated communication signals with anoptimized gate bias value. The amplifier shows during the final tests high-efficiencylevels of up to 40% and is still able to behave linearly with>20 dB gain and lowerror vector magnitude below 1%.The fundamental theory for signal processing is described at the beginning of thereport, followed by an overview of the experimental setup built during the thesis formeasuring modulated signals through amplifiers.
