RFFM6403

2.5V to 4.2V, ISM Band, 1W, 405MHz to 475MHz

Transmit/Receive Module

The RFFM6403 is a single-chip front end module (FEM) for applications

in the 405MHz and 475MHz ISM Bands. The RFFM6403 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,

SP2T Antenna switch, integrated Tx harmonic filter, 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 greatly minimizes next level board space and

allows for simplified integration
