Product Description

The SE2554L is a complete 802.11 b/g WLAN RF

front-end module providing all the functionality of the

power amplifier, power detector, T/R switch, diversity

switch and associated matching. The SE2554L

provides a complete 2.4 GHz WLAN RF solution from

the output of the transceiver to the antennas in an

ultra compact form factor.

The SE2554L is designed for ease of use, with all the

critical matching and harmonic filtering integrated,

offering a simple 50 Ω interface to the antenna. The

SE2554L also includes a transmitter power detector

with 20 dB of dynamic range and a digital enable

control for transmitter power ramp on/off control. The

power ramp rise/fall time is 0.5 μs typical.

The device also provides a 3.2–3.3 GHz notch filter

prior to the input of the power amplifier.
