Overview: RFFM6404
2.5V to 4.5V, ISM Band, 27.5dBm, 430MHz to 450MHz Transmit/Receive Module
The RFFM6404 is a single-chip front end module (FEM) for applications in the 430MHz and 450MHz ISM Bands. The RFFM6404 addresses the need for aggressive size reduction for typical portable equipment RF front-end design and greatly reduces the number of ponents outside of the core chipset thus minimizing the footprint and assembly cost of the overall solution. The RFFM6404 contains an integrated 27.5dBm PA, SP2T Antenna switch, integrated Tx harmonic filter, LNA with bypass mode, and matching ponents. The RFFM6404 is packaged in a 28-pin, 6.0mm x 6.0mm x 0.975mm over-molded laminate package with backside ground which greatly minimizes next level board space and allows for simplified integration.
