Product Description
The SE5502L 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
SE5502L 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 SE5502L 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 SE5502L packaged in 4mm x 4mm x 0.9mm,
Halogen free, Lead free, ROHS compliant, MSL 3
QFN package.
