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.
