The Air Force Research Laboratory Sensors Directorate and the Wright Brothers Institute hosted the Gallium Nitride (GaN) Radio Frequency (RF) Power Amplifier Design Challenge kick-off session, Jan. 28, in Dayton, Ohio. The goal of this challenge is to lower barriers to entry to advanced GaN technology, engage with non-traditional GaN power amplifier designers, and foster domestic design and fabrication capabilities.
