Product Description
The SE2559L20 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 SE2559L20
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 SE2559L20 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
SE2559L20
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.
