Part No. Package Remark SE2545A23 48 pin LGA Samples SE2545A23-R 48 pin LGA Tape & Reel SE2545A23-EK1 N/A Evaluation kit Product Description The SE2545A23 is a complete 802.11n WLAN RF front-end module providing all the functionality of the power amplifiers, power detector, T/R switch, 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 trans ceiver 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. Each transmit chain has a separate digital 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.
