mmW long range communications challenges Spectrum allocation mmW outdoor channel models Antennas: directionality Increasing antenna and RF efficiencies High gain power amplifier Digital BB CMOS implementation Low power, area & cost effective solutions



Terahertz

Transition region between Electronics and Photonics: λ = 1mm‐0,1mm

Measurement instrumentation is scarce and expensive THz communications: spectrum not yet allocated above 0,3THz THz electronics limited by the device performance (Ft, Fmax) IEEE 802.15 WPAN Terahertz Interest Group (started from 2008)



THz chip to chip communication Target: replace high speed wired links that requires complex networking in

a limited area. Terahertz advantages: wide bandwidth allows to provide tens of Gb/s data

rate for chip to chip or intra chip communication Smaller antenna size reducing die area and cost



To conclude mmW communications require high performance components

implementing radio access technologies: CEA‐LETI is developing prototypes.

Some key challenges Spectrum allocation Propagation Antennas design: directionality, beamforming RFFE, including high gain PA Digital BB Energy efficiency Versatile and reconfigurable ICs covering several standards CMOS implementation (CMOS bulk or SOI (65nm, 28nm)) Area & cost effective solutions
