Applications
Product Description



The SE2579U is a complete 802.11 b/g/n WLAN RF
front-end module with a Bluetooth port. The device
provides all the functionality of the power amplifier,
power detector, filter, Switch, Low Noise Amplifier,
2170 MHz notch filtering and associated matching.
The SE2579U provides a complete 2.4 GHz WLAN
RF solution from the output of the transceiver to the
antennas, and from the antennas to the input of the
transceiver, in an ultra compact form factor.

The SE2579U is designed for ease of use, with all the
critical matching and harmonic filtering integrated,
also offering a simple 50 Ω interface to the antenna.
The SE2579U includes a low noise amplifier to
increase the receive sensitivity of embedded solutions
to improve range or to overcome the insertion loss of
cellular filters often included for mobile applications. It
offers simultaneous WLAN and Bluetooth receive
mode.
The SE2579U also includes a transmitter power
detector with 20 dB of dynamic range and a digital
enable control for transmitter power ramp on/off
control. The power ramp rise/fall time is 0.5 μs typical.

Package Handling Information
Because of its sensitivity to moisture absorption, instructions on the shipping container label must be followed
regarding exposure to moisture after the container seal is broken, otherwise, problems related to moisture absorption
may occur when the part is subjected to high temperature during solder assembly. The SE2579U is capable of
withstanding a Pb free solder reflow. Care must be taken when attaching this product, whether it is done manually or
in a production solder reflow environment. If the part is manually attached, precaution should be taken to insure that
the device is not subjected to temperatures above its rated peak temperature for an extended period of time. For
details on both attachment techniques, precautions, and handling procedures recommended, please refer to:

“QFN solder reflow and rework information application note”, Document Number QAD-00045

“Handling, packing, shipping and use of moisture sensitive QFN application note”, Document Number
QAD-00044
