The RFFM6904 addresses the need for Equipment aggressive size reduction for typical portable equipment RF front-end Wireless Automatic Metering design and greatly reduces the number of components outside of the core Applications 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 over- molded laminate package with backside ground which greatly minimizes next level board space and allows for simplified integration.
