Single-Chip Front End Module: RFFM6901

October 17, 2012

RFFM6901RFMD’s new RFFM6901 is a single-chip front end module (FEM) for applications in the 868/915MHz ISM Band. The RFFM6901 addresses the need for aggressive size reduction for typical portable equipment RF front end design and greatly reduces the number of components outside of the core chipset, thus minimizing the footprint and assembly cost of the overall solution. The RFFM6901 contains an integrated 1W PA, dual port diversity antenna switch, LNA with bypass mode, and matching components.

The RFFM6901 is packaged in a 32-pin, 6.0mm x 6.0mm x 1.2mm overmolded laminate package with backside ground which greatly minimizes next level board space and allows for simplified integration.
