RFMD + TriQuint = Qorvo RFFM6903 RFFM6903 2.5V to 4.2V, ISM Band, 1W 915MHZ Transmit/Receive Module The RFFM6903 is a single-chip front end module (FEM) for applications in the 900MHz and 868MHz ISM Bands. The RFFFM6903 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 RFFM6903 contains an integrated 1 Watt PA, SP3T antenna switch, integrated Tx harmonic filter, Tx thru path, LNA with bypass mode, and matching components. The RFFM6903 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.
