In the first place\, channel aggregation architec tures will be presented in detail. These architectures allow cover a large band at RF without imposing containing bandwidth requirement at the lower frequency interfaces\, by combining multiple BB channels into parallel up and down conversion lanes. The design of the most critical building block s will be addressed\, as well as the packaging and module integration with the antennas\, with experimental results from fabricated prototypes. Next \, innovative techniques for the generation of the multiple LO signals req uired by these channel aggregation architecture will be presented and disc ussing\, including efficient calibration methods. Finally\, high gain ante nna architectures will be covered\, with a focus on alternatives to phased arrays for D-band and subTHz frequencies based on reconfigurable metasurf aces and transmit arrays. Overall\, this lecture will follow the thread of minimizing the energy consumption of each component of the radio transcei ver\, from the baseband interfaces up to the antenna system. The lecture w ill conclude with some applicative examples where the performances of the links will be compared with the requirements of some use cases such as bac k/front haul links and smart factory networks.\n\nBio:\nJosé Luis Gonzál ez-Jiménez is a Fellow and Research Director at CEA-Leti.
