The SE2571U 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 and
associated matching. The SE2571U 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 SE2571U 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 SE2571U 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.
The SE2571U 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.
