| SE2545A23 Dual Band 802.11n Wireless LAN Front End Preliminary Information Applications 802.11n, MIMO solutions IEEE802.11b DSSS WLAN IEEE802.11g OFDM WLAN IEEE802.11a OFDM WLAN Access Points, PCMCIA, PC cards 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 transceiver to the antennas in an ultra compact form factor. Designed for ease of use, all RF ports are matched to 50 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 sec. 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. Features 2 Transmit and 2 receive path architecture All RF ports matched to 50 Integrated 2.4 GHz PA, 5 GHz PA, TX Filter, T/R switches and diplexers Integrated Power Detector for each TX Chain 18 dBm O/P Power, 802.11b, 11 Mbits, ACPR = 32 dBc 18 dBm @ 3.0 % EVM, 802.11g, 54 Mbits 15 dBm @ 3.0 % EVM, 802.11a, 54 Mbits Single supply voltage: 3.3 V 10 % Lead free and RoHS compliant Thin lead free plated package, 10 mm x 14 mm x 1.1 mm, MSL 3 Ordering Information Part No. SE2545A23 SE2545A23-R SE2545A23-EK1 Package 48 pin LGA 48 pin LGA N/A Remark Samples Tape & Reel Evaluation kit Functional Block Diagram PU0a PU0g RX0ag TX0ag PD0ag ROg Diplexor ROa T/R Switch A0 TOg Trap Filter 2.4 GHz PA Power Detector TOa Trap Filter 5 GHz PA Diplexer Coupler T1a Trap Filter 5 GHz PA Coupler Power Detector Diplexer T1g Trap Filter 2.4 GHz PA R1a R1g Diplexor T/R Switch A1 PU1a PU1g PD1ag RX1ag TX1ag Figure 1: Functional Block Diagram 218-DST-01 Rev 1.4 May-26-2009 1 of 2 SE2545A23 Dual Band 802.11n Wireless LAN Front End Preliminary Information http://www.sige.com Email: sales@sige.com Customer Service Locations: North America: 1050 Morrison Drive, Suite 100 Ottawa ON K2H 8K7 Canada Phone: +1 613 820 9244 Fax: +1 613 820 4933 Hong Kong Phone: +852 3428 7222 Fax: +852 3579 5450 San Diego Phone: +1 858 668 3541 (ext. 226) Fax: +1 858 668 3546 United Kingdom Phone: +44 1279 464217 Fax: +44 1279 464201 Product Preview The datasheet contains information from the product concept specification.
