Bio
Aristotele Hadjichristos is a hands-on technical leader with over 30 years of experience shaping the RFIC, analog, and mixed-signal industry. His leadership and technical expertise have been instrumental in the design and shipment of approximately three billion complex ICs that power daily global connectivity. Over a career spanning from 1G to current 6G research, he has led high- impact teams at industry giants including Qualcomm, NXP, and Ericsson.He currently serves as an instructor at UC San Diego Extended Studies, where he teaches in the RF Certificate program, and as a Visiting Scholar at UC San Diego, focusing on future innovations in 6G power amplifiers. In addition, he is an active Technical Advisor to Silicon Catalyst and other pioneering startups.
Previously, he led the design of two generations of market-leading 4G/3G cellular transceivers at Qualcomm and founded the multi-billion-dollar RF Front-End (RFFE) business. At NXP, he directed global teams developing mixed-signal, mmWave, and mobile power solutions. During his tenure at Ericsson, he pioneered one of the industry’s first 2.5G (EDGE) RF platforms implementing polar modulation, and at GlobalFoundries he managed RF reference designs and strategic customer support. He began his career in Italy in the aerospace sector, designing microwave circuits for satellite applications.
He is a prolific innovator, being an inventor or co-inventor on more than 150 international patents, and has authored or co-authored eight IEEE publications.
