This means\na substantial spectral efficiency increase \, which must be achieved while maintaining or even improving the power\ne fficiency. To accomplish this one needs to employ new transmission techniq ues\, with the most promising ones\nbeing the use of mm-Wave (millimeter W ave) bands and massive MIMO (Multiple-Input and Multiple-Output)\nschemes. \nThe adoption of mm-Wave transmission is mainly due to the huge bands ava ilable. Moreover\, the small wavelength\nmeans small antennas\, allowing s mall-sized transmitter and receivers with very high number antenna element s and\,\ntherefore\, enabling massive MIMO implementations. However\, thes e frequencies present considerable challenges\nboth in terms of propagatio n (high propagation free-space path losses\, small diffraction effects and almost total\nabsorption losses due to obstacles) and implementation (nam ely at the power amplification level). Therefore the\ndesign of mm-Wave co mmunications with high power and spectral efficiencies presents a consider able challenge.\nIn this tutorial we start by making an overview on the co nstraints on power and spectral efficiencies and techniques\nto improve th em. Then we present quasi-linear amplification techniques based on multipl e strongly nonlinear\namplifiers that allow a highly efficient amplificati on. Finally\, we consider the path and challenges that we faced for\nthe p ractical implementation of those amplification schemes\, from patents to a potential product.\n\nRui Dinis received the Ph.D. degree from IST\, Tech nical University of Lisbon\,\nPortugal\, in 2001 and the Habilitation in T elecommunications from FCT\, Nova\nUniversity of Lisbon (UNL)\, in 2010.
