Product Description
The RF5385 provides an integrated front-end solution for WiFi 802.11b/g/n and
Bluetooth® systems. The ultra small form factor package and integrated matching
greatly reduces the number of external components and layout area in the cus-
tomer application. This simplifies the total Front-end solution by reducing the bill of
materials, system footprint, and assembly cost.

The RF5385 integrates a 2.4GHz Power Amplifier (PA), 2170MHz notch filter for
coexistence with cellular radios, second harmonic attenuation, power detector cou-
pler for improved accuracy, and a SP3T switch capable of simultaneous reception
for WiFi and Bluetooth®. The device is provided in a 2.5mmx2.5mmx0.5mm, 12-
pin package. This module meets or exceeds the RF Front-end needs of IEEE
802.11b/g/n WiFi RF systems.
