Product Description
The RF5288 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 RF5288 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 therefore minimizing the footprint and
assembly cost of the overall 802.11a/b/g solution. The FEM contains integrated power amplifi-
ers for 2.5GHz and 5GHz, TX/RX switch for each band, low noise amplifier for the 5.0GHz
receive band, matching components, bypass capacitors, built-in power detector for both bands,
and band pass filters for both transmit paths and some filtering for both receive paths. The
device is manufactured on lead frame with InGap HBT and pHEMT processes. The RF5288
module is a 5mmx5mmx0.9mm package with 32-pins and a backside ground. The RF5288
greatly minimizes next level board space and allows for simplified integration.
