Radio Frequency Integrated Circuits Research Group

Dr. Prasad Gudem earned a B.Tech degree in Electrical Engineering from the Indian Institute of Technology, Madras, India, in 1988, and a Ph.D. degree in Electrical Engineering from the University of Waterloo, Ontario, Canada, in 1996. During his tenure at Qualcomm from 2002 to 2018, he led the development of groundbreaking transceiver technologies, including the first integrated diversity receiver chip, the first integrated SAW-less receiver for CDMA2000, and the first carrier aggregation multi-mode multi-band transceiver on 28-nm and 14-nm nodes. These world-class transceiver products (RFR6500, QSC1100, WTR3925, and SDR855) collectively achieved over 2 billion unit shipments worldwide.
From 2014 to 2018, he served as Vice President of Engineering at Qualcomm and has been an adjunct faculty member with the Department of Electrical and Computer Engineering at UC San Diego since 2014. Dr. Gudem has co-advised over 20 Ph.D. students in Analog/RF integrated circuit (IC) design, authored over 50 IEEE publications, and holds more than 50 patents. He has taught advanced graduate-level courses, including the ECE265 sequence, “Communication Circuit Design: I, II, and III,” earning the Graduate Teaching Award for his exceptional contributions to education.
Dr. Gudem’s research interests span Analog/RF IC design and communication circuit innovation. Outside of engineering, he is an avid enthusiast of STEM history and enjoys boomerang sports.
