Abstract: Distributed amplifiers (DA) are critical components in various applications such as electronic measurement instruments, high-speed wireless systems, RADAR, and optical networks. In this lecture an introduction to distributed amplifiers and their applications will be presented. After this a feedforward intermodulation design technique to improve linearization will be discussed. Finally, a prototype utilizing this new technique will be presented.

Bio: Dr. Alexander Stameroff received a BS, MS, and PhD in Electrical Engineering from the University of California, Davis in 2007, 2011, and 2013, respectively. His PhD was in the field of high efficiency power amplifiers in X-band for RADAR applications. He joined Keysight Technologies (then Agilent) in 2013 as an Integrated Circuit designer. In 2020 he became manager of Keysight’s RF/mmWave Subsystem Design group. He has also been an adjunct professor with Santa Rosa Junior College since 2015. He has authored and co-authored over 20 publications in his field.
