Product Description
The SE2545A30 is a complete 802.11n WLAN RF
front-end module providing all the functionality of the
power
diplexers and associated matching. The SE2545A30
provides a complete 2.4 GHz and 5 GHz WLAN
Multiple Input, Multiple Output (MIMO) RF solution
from the output of the transceiver to the antennas 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 SE2545A30 also includes a
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 0.5
μsec.
The device also provides a notch filter from 3.2-3.3
GHz and 3.2-3.9 GHz prior to the input of each 2.4
GHz and 5 GHz power amplifiers, respectively.
