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.
