RFFM6406
2.5V to 4.2V, ISM Band, 1 1/2W, 408MHz to 455MHz
Transmit/Receive Module
The RFFM6406 is a single-chip front end module (FEM) for applications
in the 400MHz ISM Band. The RFFM6406 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 RFFM6406 contains an integrated 1 1/2 Watt PA,
SP2T antenna switch, integrated Tx harmonic filter, LNA with bypass
mode, and matching components. The RFFM6406 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
