High power, high efficiency, wide bandwidth amplification using optically sourced isolated switch elements

Summary form only given, as follows. A novel RF/Microwave amplifier is described which shows high power and efficiency over four decades of bandwidth with dimensions smaller than any existing technology. The amplifier uses a voltage-mode Class-D configuration. Optical connections provide electrical isolation to each element. Simulations show output powers greater than 150W with drain efficiencies of at least 55% at bandwidths up to 2 GHz. A fabricated circuit validates the basic amplifier concept and shows initial capabilities.
