SE2579U

2.4 GHz High Efficiency Front-End for Wireless LAN and a Port Suitable for Bluetooth® Applications


The SE2579U is a complete 802.11 b/g/n WLAN RF front-end module with a port suitable for Bluetooth® signals. The device provides all the functionality of the power amplifier, power detector, filter, switch, low noise amplifier, 2170 MHz notch filter 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 receive mode for a port suitable for Bluetooth® signals.

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.
