The RFFFM6403 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 RFFM6403 contains an integrated 1 Watt PA, SP3T Antenna switch, integrated Tx harmonic filter, Tx thru path, LNA with bypass mode, and matching components. The RFFM6403 is packaged in a 28-pin, 6.0mm x 6.0mm x 0.975mm over-molded laminate package with backside ground which great...
