The RFFM6904 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 RFFM6904 contains an integrated 2 Watt PA, TX/RX transfer switch, LNA with bypass mode, and matching components.
The RFFM6904 is packaged in a 32-pin, 8.
0mm x 8.
0mm x 1.
2mm overmolded laminate package with backside ground which greatly minimizes next level board space and allows for simplified integration.
