Technology Overview - mm-wave SiGe ICs

Increasing consumer demand for high data-rate wireless applications has resulted in development activity to exploit the mm-wave frequency range where large amounts of spectrum are available. The ISM band around 60GHz (V-band) and the light-licensed spectrum at E-band (71-76GHz and 81-86GHz) are of particular interest. Whilst commercial mmwave ICs have traditionally been realised using III-V based processes, the increasing availability of SiGe processes with very high Ft's offers an alternative solution benefiting from the potential for lower unit costs in volume production.
