Product Description

The SE2613T 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, harmonic

filtering, switch, low noise amplifier (LNA), and

associated matching. The SE2613T provides a

complete 2.4 GHz WLAN RF solution from the output

of the transceiver to the antenna, and from the

antenna to the input of the transceiver, in an ultracompact

form factor.

The SE2613T 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 SE2613T 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 for mobile applications.

The SE2613T also includes a transmitter power

detector with 20 dB of dynamic range and a digital

enable control for transmitter power ramp on/off

control.
