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.
