Description

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.
