Keywords:EPCOS? MOBILIS? BAW filter? RF filter?

Epcos announced that it has recently joined a new European Union (EU) program known as MOBILIS.

The objective of the program is to develop miniaturized RF filters for the latest mobile phone standards and digital radio reception with mobile phones. In particular, Epcos will contribute its know-how in bulk acoustic wave (BAW) technology in the project.

The MOBILIS participants expect to develop BAW solidly mounted resonators on a silicon basis, which on a single chip cover all mobile communications standards and frequency bands as well as additional services. The challenge is to develop a process that combines low insertion loss with high power compatibility as well as high linearity, low costs and a minimum form factor. Over the long term, this solution will be integrated into mobile phone chipsets as an SoC in order to achieve an even higher level of miniaturization.
