Product Description

The SE2548A 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 SE2548A

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.

The SE2548A packaged in 5mm x 5mm x 1.0mm,

Halogen free, Lead free, ROHS compliant, MSL 3

LGA package.

Each transmit chain has a separate digital
