SE2611T

2.4 GHz High Efficiency Front End for WLAN and Bluetooth® Applications

The SE2611T is a complete 802.11 b/g/n WLAN RF front-end module comprising a port suitable for Bluetooth® signals. The device provides all the functionality of the power amplifier, power detector, filter, switch, low noise amplifier (LNA), 2170 MHz notch filtering and associated matching. The SE2611T 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 SE2611T is designed for ease of use, with all the critical matching and harmonic filtering integrated, while also offering a simple 50Ω interface to the antenna.

The SE2611T includes an LNA to increase the receive sensitivity of embedded solutions to improve range or to overcome the insertion loss of cellular filters often included in mobile applications.

The SE2611T 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.
