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.
