The RF5516 provides a complete integrated solution in a single Front-End Module (FEM) for WiFi 802.11a systems. The ultra small form factor and integrated matching minimizes the layout area in the customer's application and greatly reduces the number of external components to only one bypass capacitor for supply decoupling. This simplifies the total Front-End solution by reducing the bill of materials, system footprint, and manufacturability cost. The RF5516 integrates a Power Amplifier (PA), Single Pole Double Throw switch (SP2T), Low Noise Amplifier (LNA), and a power detector coupler for improved accuracy. The device is provided in a 3mm x 3mm x 0.5mm, 16-pin package. This module meets or exceeds the RF Front End needs of IEEE 802.11a WiFi RF systems.
