Challenging CMOS with beamforming in the D-band
Wireless communication in the D-band inevitably needs beamforming to obtain a decent link budget. While fully digital beamforming yields too much overhead in power and area, analog beamforming, at least partially, will be needed. This talk discusses how different beamforming architectures perform in CMOS, given the high operating frequency and the large RF bandwidth that is needed for high data rates.
