Functional Block Diagram
Product Description
The RF5389 is a single-chip dual-band integrated front-end module (FEM) for highperformance WLAN applications in the 2.5GHz and 5GHz ISM bands. The RF5389 addresses the need for aggressive size reduction for typical 802.11a/b/g and 1x2 11n MIMO 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 and 11n solution. The RF5389 contains integrated PA's for 2.5GHz and 5GHz, diplexers, TX/RX switch, dual LNA's for high receive bands, matching components, some bypass capacitors, built-in power detector for both bands, and filtering for transmit and receive paths. The RF5389 is packaged in a 40-pin, 6mmx6mmx0.95mm QFN package with backside ground which greatly minimizes next level board space and allows for simplified integration.
