Product Description
The RF5388 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 RF5388
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/n solution. The RF5388 contains integrated PA’s for 2.5GHz and
5GHz, diplexers, TX/RX switch, LNA for the 5.0GHz receive band, matching compo-
nents, some bypass capacitors, built-in power detector for both bands, and filters
for transmit and receive paths. The RF5388 is packaged in a 40-pin,
6mmx6mmx0.9mm QFN package with backside ground. Greatly minimizes next
level board space and allows for simplified integration.
