Abstract

Wireless local networks and remote identification systems are emerging in the 5.2GHz to 5.8GHz Telecommunication link networks for inter-cell connections are to a high degree based on radio links in the frequency range between 13GHz and 6OGHz. At 76GHz the first automotive radars are now available and in use. For these applications state of the art GaAs components are developed and provided by European sources. Up to X-band MESFETs are still carrying the load whereas else heterostructure transistors become dominant. This paper reviews the Activities from a European point of view.
