Product Description

The SE5511T is a complete 802.11n WLAN RF front-

end module providing all the functionality of the power

amplifiers, LNA, power detector, Antenna switches,

filtering and associated matching. The SE5511T

provides a complete 2.4 GHz and 5 GHz WLAN RF

solution from the output of the transceiver to the

antennas in a compact form factor.

The

receive

path

is

designed

to

maximize

performance by providing both a 5 GHz Low noise

amplifier with bypass mode, for use when high power

signals are being received.

Designed for ease of use, all RF ports are matched to

50

Ω to simplify PCB layout and the interface to the

transceiver RFIC.

The SE5511T also includes a

transmitter power detector for each band with 20 dB

of dynamic range.
