Advanced III-V HEMT Technology for Microwave and Millimetre-Wave Applications

This paper describes the current European status of HEMT technology for analogue MMIC applications at microwave and mm-wave frequencies. Results from three European Foundries (GEC-Marconi, Philips and Thomson) will be presented to illustrate the position. The key technology issues will be discussed, including the requirement for high quality epitaxial material. This latter point has been addressed commercially by both MBE (Picogiga) and MOVPE (Epitaxial Products International) growth techniques.
