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. The SE2547A also includes a
transmitter power detector for each band and transmit
chain 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.
