RF3388
3.7V, DUAL-BAND FRONT-END MODULE
The RF3388 is a single-chip dual-band integrated front-end module (FEM) for high-
performance WLAN applications in the 2.5GHz and 5GHz ISM bands. The RF3388
addresses the need for aggressive size reduction for a typical 802.11a/b/g 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
802.11a/b/g solution. The RF3388 contains integrated PA’s for 2.5GHz and 5GHz,
TX/RX switch for each band, LNA for the 5.0GHz receive band, baluns for both low
and high receive bands, some bypass capacitors, built-in power detector for both
bands, and some filtering for transmit and receive paths. The RF3388 is packaged
in a 24-pin, 4mmx4mm QFN package with backside ground. The RF3388 greatly
minimizes next level board space and allows for simplified integration.
