ABSTRACT

—The130-175 GHz frequency spectrum, identified as D-band, will be the key-enabler for next-generation back- hauling point-to-point wireless links. Since capacity requirements for mobile networks will increase according to 5G/ B5G deployment needs, a new paradigm for radio equipment needs to be devel- oped. Integrated technologies based on silicon-germanium, exhibiting sub-THz cut-off frequency, are going to be adopted to design and implement the key building blocks for fully integrated transceivers. D-band radio frequency integrated circuits and antenna concepts are presented, tailoring phased array allowing electronic beamsteering and beamforming features.
