Abstract
We report the first demonstration of Class B push-pull operation of AlGaN/GaN HEMTs on SiC substrates, thereby taking advantage of lower thermal dissipation while achieving linear operation and allowing higher power density in large-area devices. This lower thermal dissipation can be achieved because of the potentially higher power-added-efficiency (PAE) of Class B operation, relative to Class A operation.
