RF3688 2.4GHz to 2.5GHz and 4.9GHz to 5.85GHz, 802.11 b/g/a/n Dual-Band FEM

The RF3688 is a single-chip dual-band integrated front end module (FEM) for high-performance WiFi applications in the 2.5GHz and 5GHz ISM bands. The RF3688 addresses the need for aggressive size reduction for a typical 802.11a/b/g/n 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 RF3688 contains integrated PAs for 2.5GHz and 5GHz, Tx/Rx switch for each band, baluns for both low and high receive bands, some bypass capacitors, built-in power detector for both bands, and some filtering for transmit paths. The RF3688 is packaged in a 24-pin, 4mm x 4mm QFN package with backside ground. The RF3688 greatly minimizes next level board space and allows for simplified integration.
