Dual Band 802.11n Wireless LAN Front End

Product Description

The SE2545A23 is a complete 802.11n WLAN RF

front-end module providing all the functionality of the

power

diplexers and associated matching. The SE2545A23

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 SE2545A23 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.
