RF MEMS: status of the industry and roadmaps
暂无分享，去创建一个
Microsystems for radio frequency applications, known as RF MEMS, have entered the commercialization phase in 2003. Bulk acoustic wave filters are already produced in series and first commercial samples of switches are available. On the other hand, reliability and packaging problems are still a major hurdle, especially for switches and tunable capacitors. This presentation gives an overview of RF MEMS applications and market players. The paper highlights technical challenges that still have to be solved to open mass markets such as mobile telephony and WLAN. The presentation also presents applications of RF MEMS and opportunities in niche markets with high added value like military and space applications. WTC provides a regional analysis and compares R&D focus and public funding situations in North America, Europe and Asia. Finally, the paper presents an updated product roadmap market forecast for RF MEMS devices for the 2004-2009 time period.
