Product Description
The SE2585L is a complete 802.11 b/g WLAN RF
front-end module with a Bluetooth port. The device
provides all the functionality of the power amplifier,
power detector, filter, SP3T switch and associated
matching. The SE2585L 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 SE2585L is designed for ease of use, with all the
critical matching and harmonic filtering integrated, and
offering a simple 50 Ω interface to the antenna. The
SE2585L 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.
