Product Description
The RF5389 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 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 out-
side of the core chipset thus minimizing the footprint and assembly cost of the over-
all 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.
