SE2571U-EK1

SE2571U 2.4 GHz High Efficiency Wireless LAN/BT Front End Preliminary Applications IEEE802.11b DSSS WLAN IEEE802.11g,n OFDM WLAN Embedded applications with Bluetooth (Mobile) Product Description 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.
