SE2611T: 2.4 GHz High Efficiency Wireless LAN/BT Front End
Applications
IEEE 802.11b DSSS WLAN
IEEE 802.11g/n OFDM WLAN
Embedded applications with Bluetooth
®
(Mobile)
Description
The SE2611T 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 (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, also offering a simple
50
interface to the antenna.
The SE2611T 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 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
s
typical.
The device package and pinout for the 20-pin QFN are shown in
Figure 1. A block diagram of the SE2611T is shown in Figure 2.

Note 1:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
