A Fundamental Key to Next-Generation Directed-Energy Systems
Abstract
Naval Surface Warfare Center, Dahlgren Division (NSWCDD), is meeting the demanding requirements of next-generation Directed-Energy (DE) systems with Class-E radiofrequency (RF) transmitter switch-mode amplifiers designed to operate at ultrahigh efficiency, greater than 90 percent. Having discovered the key to next-generation DE systems, researchers at NSWCDD are focusing on the urgent need to counter-improvised explosive device (IED) systems with small, lightweight, highly efficient transmitters that use switch-mode amplifiers. Considering the multiplicity of additional applications, all advancements made in amplifier counter-IED applications can be transferred to other applications in the future. Accordingly, while the capabilities suggested in this article might seem somewhat far-fetched, in reality, they are realizable in the near term. It is projected that NSWCDD will soon have its first 250-W ultrahigh frequency (UHF) amplifier unit prototype ready. These units will fit in the palm of an average-sized adult's hand and can be power combined to the level necessary for platform and mission requirements. A fully realized, fieldable DEW system prototype is possible in just a few years.
