Objectives and Approach

The overall objective of COSMIC was the development of GaAs MMICs for microwave communication systems up to 23 GHz. Multifunction MMICs in MESFET/HEMT technology, which are complete or core parts of receiver units, were realised. The systems considered were:

Improvements in some basic properties of the following central issues were considered necessary:

Progress and Results

The major results were:

All demonstrators were achieved. Commercialisation of the resulting products has already started, especially in the area of mobile telephones.
