Politecnico di Torino RF Characterization and reliability of a power amplifier cell under large signal operation. Student: Javier A. Monguilo Mantovani ID: 263724 ABSTRACT The development of wireless communications is, perhaps, one of the most important technological advances humanity ever reached. Indeed, trying to imagine the contemporary World without any form of wireless network is almost impossible. From data transfer through smartphones that keep people connected, up to radars that keep air traffic safe close to airports, among many other applications, wireless systems play a significant role in modern life, guaranteeing not only commodity, but also safety. These advances have made humanity considerably dependent on the correct functioning of the wireless network infrastructure.
