  • Abstract
    This work explores wideband efficiency enhancement techniques for distributed amplifiers. The concept of a supply-scaled distributed amplifier (SSDA) utilizing a band-pass distributed amplifier with multiple supply voltages is discussed. A prototype amplifier is fabricated in a 0.15μm GaN on a 2mil SiC process. The chip is measured and shows a significant improvement in drain efficiency and power added efficiency with supply scaling.
