The MEMS-4-MMIC proposal aims at the integration of RF-MEMS switches onto Monolithic Microwave Integrated Circuits (MMIC) creating highly integrated multifunctional building blocks for high-value applications. RF-MEMS will be an essential building block of next-generation smart systems that are characterised by cost-effective and compact designs, high performance, flexibility and configurability.MEMS-4-MMIC will consider the whole value chain of RF-MEMS MMIC components starting at the materials and suitable foundry processes, the RF-design, packaging of RF-MEMS MMIC, and last but not least, the testing and reliability which plays a very important role in the whole manufacturing/commercialisation process. For this purpose one of Europe's leading GaAs MMIC foundries is part of the consortium. The definition of first RF-MEMS MMIC components starts with the selection of the correct requirements that are dictated by next-generation wireless smart applications, automotive radar, satellite terminals, 60 GHz WLAN and cognitive radio frontends. As a proof-of-concept an RF-MEMS MMIC based antenna module will be realised at the end of project showing the innovative character and possibilities for commercial exploitation.The MEMS-4-MMIC project will significantly contribute to the knowledge and competence to include RF-MEMS switches on existing GaAs MMIC foundry processes. The project aims to provide the enabling technology platform needed for the future establishment of an RF-MEMS MMIC manufacturing base within Europe.If successful, MEMS-4-MMIC will speed-up the commercialisation of RF-MEMS MMIC components for small scale as well as large scale production (shorten time-to-market), and be accessible for all types of customers, thus turning RF-MEMS MMIC technology into pure profit for Europe wireless highway of tomorrow.
