David Lopez Bueno received his MSc. degree in Telecommunications Engineering from the Universitat Politècnica de Catalunya (UPC) in 2005 and a Postgraduate certificate in Education (Mathematics) from the Universidad Complutense de Madrid (UCM) in 2007.

Between 2003 and 2006 he worked near 4 years as RF design engineer at Mier Comunicaciones and Alcatel Alenia Space España (now Thales Alenia Space España) participating in the design, implementation and validation of RF/uW modules and MMIC devices for satellite payloads (AMHERIS/AMAZONAS, TRMO, Galileo ISBT TTC Transponders and ICO G1 programmes).

By the end of 2006, he joined the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) as Research Engineer where he has contributed to several national and European publicly funded projects (MIMOWA, BuNGEE, BeFEMTO, GEDOMIS-ADCOMM, GRE3N, EMPhAtiC, Flex5Gware and HIPOCRATES-AEThER, from 2006 to 2018) by: i) building multi-band RF Transceivers and contributing to lab demonstrators validating 4G/5G MIMO OFDM-based schemes such as the GEDOMIS® testbed; ii) evaluating the coexistence between heterogeneous systems in spectrum sharing scenarios and the transceiver energy trade-offs; iii) conceiving wideband high-end modular radios; and iv) researching and designing digital linearization techniques, such as crest factor reduction (CFR) and digital predistortion (DPD), for wideband radio access and wireless backhaul infrastructure transmitters, and building the experimental demonstrators for RF/uW/mmW applications such as the SHAPER platform.

At CTTC, he has also been involved in industrial projects assessing the risk of interference between FS and FSS systems in rural Europe (ROSE-ERO, 2011) and, in the last years, aiming at researching and experimental benchmarking wideband PA linearization techniques and efficient transmitter architectures for backhaul equipment (DI-PRE-DATORS, 2012-2013), 5G radio access transmitters (FUTURETX, ITERATE, 2017-2018) and cable TV systems (DPD4CABLE, 2017-2018).

David is Researcher at CTTC’s PHYCOM department since 2013 and Coordinator of the Radio Technologies Laboratory since 2009. David is currently pursuing a PhD thesis in resource-efficient digitally driven PA Linearization strategies for 5G Radio Equipment. He is IEEE member since 2013, IEEE Senior Member since 2018,  and regular reviewer of a number of IEEE journals.
