Ali Darwish
Ali Darwish, Ph. D., received his Ph.D. degree from Massachusetts Institute of Technology (MIT), Cambridge, MA, in 1996. In 1990, he joined COMSAT Laboratories where he conducted the experimental work on his M. S. thesis. In 1992, he joined the Optics and Quantum Electronics Group, MIT as a research assistant. In 1997, he co-founded Amcom Communications Inc., a leading supplier of high power microwave integrated circuits. At Amcom Communications he served as the vice president of product development where he designed and commercialized several product lines. Dr. Darwish designed several state-of-the-art monolithic microwave integrated circuits (MMICs) including an X-band low phase noise oscillator, broadband high power amplifiers (in the L-, S-, X-, Ku-, and Ka-band), mixers, a DC-40 GHz digital attenuator, phase shifters, and charge pumps. He also built and tested a 1000-Watt linearized amplifier for WCDMA base stations, a high efficiency 200-Watt S-band amplifier, and a Ku-band packaged power amplifier MMIC for very small aperture terminal (VSAT) applications.
Dr. Darwish is an adjunct faculty member at University of Maryland, Baltimore County, MD where he teaches a course on RF and mixed-signal circuit design. He has published over 30 technical articles, and has developed a number of short courses on microwave circuit design. He is currently conducting research on thermal effects in MMICs, and innovative power amplifier topologies.
