Dr. Harvey received his B.S.E.E. and Doctor of Engineering degrees from Morgan State University as well as an M.S.E.E degree from University of California Los Angeles. As a prominent engineer in the area of Microwave and Millimeter-wave monolithic circuit design as well as characterization and modeling of active III-V compound semiconductor devices, Dr. Harvey has worked on state of the art technology for satellite and terrestrial communication and electronic warfare systems. Some notable establishments that have utilized Dr. Harvey’s knowledge and service over the years include HRL Laboratories, Applied Wave Research, Raytheon, Applied Physics Laboratories, ViaSat, NASA-Goddard, Space Systems Loral and Northrop Grumman. Along his technology journey, Dr. Harvey developed a passion for teaching through many internal corporate training opportunities as well as formal and informal university adjunct roles. Coupled with an equally notable passion for research and innovation, Dr. Harvey now assumes the role as a researcher and educator at Morgan State University.

 

Dr. Harvey’s research interest includes reconfigurable and adaptable Microwave and Millimeter-wave communication systems as well as supporting and enabling technologies in the area of intelligent control of aforementioned systems, with potential use in modern detection systems. Currently, Dr. Harvey is in the process of developing a W-Band Gallium Nitride (GaN) based Power Amplifier (PA) and power combiners/dividers to support a novel W-Band transceiver architecture. This effort is part of a future trajectory of the development of both a MMIC based Gallium Nitride (GaN) based multi-band selectable PA and a multi-band selectable Low Noise Amplifiers (LNA) for reduced-scale receiver and detector systems. The novelty of the band-selectable LNA and PA circuits is that they utilize tunable elements controlled by limited number of switches without decoding, in a topology that minimize path losses.

 

With a keen eye on the future, Dr. Harvey is also laying the groundwork for the development of digitally augmented tunable radios for flexible and dynamically controlled communication and radiometry systems for terrestrial and space applications. This would essentially be an extension of the aforementioned work, with pursuit of more efficient and effective strategies to implement functions like phase alignment and gain control in the digital domain using Field Programmable Gate Arrays (FPGAs) or software defined radios (SDRs). This strategy, couple with improve efficiency, linearity and output power of PAs as well as improved gain, noise figure and intermodulation characteristics of LNAs, would significantly advance the tunable radio state of the art. Dr. Harvey not only intend to push the boundaries of traditional Microwave and Millimeter-wave circuit design, but he is forging a new path to exploit the convergence of RF/Microwave, analog, and digital technologies for the benefit of advanced, highly integrated, intelligent systems.
