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.
