EASY-A

Enablers for Ambient Services & Systems - Part A - 60 GHz Broadband Links

Objective

The project goal is the developement of wireless communication systems using the 60-GHz band. In this frequency band new techniques like beamforming or antenna diversity will be investigated. The integration of this 60-GHz technology into other radio standards will be explored.

Because of the different requirement profiles for 60-GHz applications different modulation techniques will be required too. (1) For short-distance-systems with a maximum of 1 meter a line-of-sight-connection without multi path effects can be assumed. In this case simple single-carrier-techniques can be used. (2) For longdistance-systems multi path effects have to be accounted for, so more complex techniques like OFDM shall be the better choice. The goal of IHP is to develop a chip set, which covers different transmission-modes.

To reach the extreme high data rates of some GBit/s, new techniques and architectures become necessary for analog front-end (AFE), baseband (BB) and media-access-control (MAC). Higher integration of these components will reduce the manufacturing costs. IHP's own SiGe:C-BiCMOS technology is extremely well suited for this purpose.

The project results will be used in the corresponding standards. Currently IHP contributes actively to the 60-GHz-standardization within IEEE802.15.3c.

IHP`s Contribution

  • High integration of front-end chips to decrease the system costs.
  • Different modulation techniques on a single chip.
  • Improve the signal-noise-ratio and the phase-noise.
