Product Description

The SE5512L is a complete 802.11a/b/g/n WLAN RF

front-end module providing all the functionality of the

power amplifiers, filtering, power detector, T/R switch,

diplexers,

LNA

and

associated

matching.

The

SE5512L provides a complete 2.4 GHz and 5 GHz

WLAN RF solution from the output of the transceiver

to the antenna in an ultra compact form factor.

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 SE5512L also includes a

transmit power detector with 20 dB of dynamic range

for each transmit chain. Each transmit chain has a

separate digital enable control for transmitter power

ramp on/off control. The power ramp rise/fall time is

less than 0.7

μsec.

The device also provides a notch filter from 3.260-

3.267 GHz and 3.28-3.89 GHz prior to the input of

each

2.4

GHz

and

5

GHz

power

amplifiers,

respectively.

The SE5512L packaged in 4mm x 4mm x 0.9mm,

Halogen free, Lead free, ROHS compliant, MSL 3

QFN package.
