  • Abstract
    The combination of gallium nitride (GaN) device technology with the now well established efficiency enhancing Doherty power amplifier (PA) architecture is presented for the first time. The experimental structure exhibits a power density of approximately 1 W/mm and linearity that remains comparable to that observed in other GaAs structures, demonstrating that GaN can be highly effective when used within this type of PA architecture.
