Abstract. In the frame of North Star AMICOM ReRaFE (Reconfigurable Radio Frond-End) project, a new kind of MEMS multi-band filter has been designed. This device is optimized to perform frequency selective operations in a radio front-end subsystem, switching between two very different standards: DCS1800 at 1.84 GHz with a 4% fractional bandwidth (FBW), and WLAN at 5.2 GHz with a 17% FBW. Nevertheless the original principle presented can be applied to different central frequency and bandwidth sets.
