Product Description
The SE2594L 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 and associated matching. The SE2594L
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 SE2594L 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.
The SE2594L packaged in 5mm x 5mm x 0.9mm,
Halogen free, Lead free, ROHS compliant, MSL 3
QFN package.
