Apr 29 (Fri) @ 11:00 am: "MaxLinear Overview & Microwave Backhaul System Tutorial," Vamsi Paidi, MaxLinear

Abstract

Presentation starts with an overview of MaxLinear’s most recent communications SOCs supporting the roadmaps for data centers, wireless and home networking infrastructure. To realize full 5G connectivity potential, enhancing and modernizing microwave backhaul system is essential. In this talk, we focus on microwave backhaul system as case study example. After introducing this system at high level, techniques to achieve enhanced throughput discussed. These techniques involve pushing all available degrees of freedom, such as, complex modulation, carrier aggregation, antenna polarization and MIMO. Roadblocks and challenges realizing best possible throughput will be discussed and solutions debated. Walk-through of example link budgets performed to identify critical performance bottlenecks and to showcase how a practical system rises to meet these challenges. Talk concludes exploring frontend module (FEM) design considerations and digital pre-distortion (DPD) nuances to achieve best link performance while meeting transmitter emission mask.

Bio

Vamsi Paidi received his bachelor’s degree from Indian Institute of Technology, Chennai, in 2000 and his PhD degree from University of California at Santa Barbara, in 2004. His doctoral work focused on mm-wave power amplifiers in gallium-nitride (GaN), and indium-phosphide (InP) technologies. He is currently Director of RF/mixed signal design at MaxLinear Inc., Irvine, California. He has done pioneering work in developing low power communication circuits and systems for microwave backhaul, cellular base stations and hyperscale datacenter applications. He has several granted US patents highlighting innovations in PLLs, front-end circuits and wireless communication systems.
