Dr. Prasad Gudem

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.
