Product Description

The SE2547A is a complete 802.11a/b/g/n WLAN RF

front-end module providing all the functionality of the

power amplifiers, filtering, power detector, Diversity

switch, diplexers and associated matching. The

SE2547A 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.

transmitter power detector for each band and transmit

chain with 20 dB of dynamic range for each transmit

chain.

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.
