In 1989, Mr. Sokal was elected a Fellow of the IEEE, for his contributions to the technology of high-efficiency switching-mode power conversion and switching-mode RF power amplification. In 2007, he received the Microwave Pioneer award from the IEEE Microwave Theory and Techniques Society, in recognition of a major, lasting, contribution development of the Class-E RF power amplifier. In 2011, he was awarded an honorary doctorate from the Polytechnic University of Madrid, Spain, for developing the high-efficiency switching-mode Class-E RF power amplifier
In 1965, he founded Design Automation, Inc., a consulting company doing electronics design review, product design, and solving ‘‘unsolvable’’ problems for equipment-manufacturing clients. Much of that work has been on high-efficiency switching-mode RF power amplifiers at frequencies up to 2.5 GHz, and switching-mode dc-dc power converters. He holds eight patents in power electronics, and is the author or co-author of two books and approximately 130 technical papers, mostly on high-efficiency generation of RF power and dc power.
During 1950–1965, he held engineering and supervisory positions for design, manufacture, and applications of analog and digital equipment.
He received B.S. and M.S. degrees in Electrical Engineering from the Massachusetts Institute of Technology, Cambridge, Massachusetts, in 1950.
He is a Technical Adviser to the American Radio Relay League, on RF power amplifiers and dc power supplies, and a member of the Electromagnetics Society, Eta Kappa Nu, and Sigma Xi honorary professional societies.
