Co-Design Block PA (Power Amplifier)-Antenna for 5G Application at 28 GHz Frequency Band
, 2022 This subject addresses the issue related to Transmitters for the new communication standard, namely 5G. Indeed to respond to the problems of radio coverage, the speed of services as well as the rise in user demand, transmitters must have ideal characteristics to be able to meet these requirements. This chapter proposes in order to answer such a problem
