Michael Cowley Jack H Lepoff

Mike Cowley received his BS and MS degrees in electrical engineering from the University of Notre Dame in 1959 and 1961, respectively. In 1965 he received the Ph.D. degree in electrical engineering from Stanford University, where he was employed as a research assistant in quantum electronics. Before coming to hp associates in 1965, he taught electrical engineering for a year at the University of California at Santa Barbara, and worked as a consultant in physical electronics.

Since joining hp associates, Mike has been concerned mainly with the thermal and noise properties of hot-carrier diodes. He has published six papers in the field of solid state device theory, and is a member of IEEE, Tau Beta Pi, Sigma Xi, and the American Physical Society.

After receiving his BS degree in physics from the University of New Hampshire in 1943, Jack Lepoff spent three years as a naval officer assigned to microwave component and antenna development at the Naval Research Laboratory. In 1946 he entered Columbia University as a graduate assistant in physics, and received his MA degree in 1948. From 1949 to 1965 he was associated with a number of firms and government laboratories, working on microwave components, radar, antennas, communications systems, parametric amplifiers, and tunnel diode amplifiers.

Jack joined hp associates in 1965, and assumed project responsibility for the spurious response rejection techniques project. He is now studying techniques for characterizing mixer diodes and methods of integrating semiconductor devices into microwave components.
