Magnetic Nanoferrites for RF CMOS: Enabling 5G and Beyond

摘要

From connected thermostats to self-driving vehicles, advanced connectivity is transforming our lives while saving energy and reducing pollution, thus making living more sustainable. This is the hallmark of the Internet of things (IoT). But the full extent of IoT possibilities is yet to be realized. One of the key foundational technologies that will serve as the core architecture for future capabilities is 5G-the 5th generation telecommunication systems. Unlike its predecessors, 5G is going to be a new heterogeneous ecosystem that includes integration of 4G, Wi-Fi, millimeter waves, and other wireless access technologies, utilizing bandwidths from various frequency bands ranging from <4 GHz to 100 GHz. Different usage scenarios demand different capabilities that can be attained in different frequency bands. As per the International Telecommunication Union (ITU), three main usage scenarios are envisaged to expand and support a diverse array of applications for International Mobile Telecommunications (IMT) 2020 and beyond, namely: 1) enhanced mobile broadband; 2) massive machine-type communications; and 3) ultra-reliable and low latency communications (as illustrated in Fig. 1), along with the key performance indicators (KPIs) associated with them.- The taming of this spectrum is considered essential to achieving the 5G vision of a truly connected world.
