RF5345

2.4GHz TO 2.5GHz, 802.11b/g/n WiFi FRONT

END MODULE

The RF5345 provides a complete integrated solution in a single Front End Module (FEM) for

WiFi 802.11b/g/n and Bluetooth® systems. The ultra small form factor and integrated match-

ing greatly reduces the number of external components and layout area in the customer appli-

cation. This simplifies the total Front End solution by reducing the bill of materials, system

footprint, and manufacturability cost. The RF5345 integrates a 2.4GHz Power Amplifier (PA),

Low Noise Amplifier (LNA) with bypass mode, power detector coupler for improved accuracy, a

2170MHz notch filter for coexistence with cellular radios, and additional filters for harmonic

rejection. The RF5345 is capable of receiving WiFi and Bluetooth® simultaneously.

The device is provided in a 3.0mmx3.0mmx0.5mm, 16-pin package. This module meets or

exceeds the RF Front End needs of IEEE 802.11b/g/n WiFi RF systems.
