| SE2576L 2.4 GHz High Power Wireless LAN Power Amplifier Preliminary Applications IEEE802.11b DSSS WLAN IEEE802.11g,n OFDM WLAN Access Points Product Description The SE2576L is a high power 802.11bgn WLAN power amplifier module providing the functionality of the power amplifier, power detector, reference voltage generator and input match. The SE2576L is designed for ease of use and maximum flexibility, with an integrated input match, and external output match to adjust the load line for 5V, 26dBm operation. The SE2576L includes a temperature compensated transmit power detector with over 20 dB of dynamic range and <1.2dB variation under 3:1 mismatch at the antenna. The SE2576L includes a digital enable control due to an integrated reference voltage generator. The power ramp rise/fall time is 0.5 s typical. Features Dual Mode IEEE802.11b, IEEE802.11g, IEEE802.11n 26 dBm, EVM = 3%, 802.11g, OFDM 54 Mbps 29 dBm, ACPR < -32 dBc, 802.11b Integrated PA, Input Match, 2.8V reference voltage generator Integrated Temperature Compensated, Positive Slope Power Detector Pb-free, RoHS compliant and Halogen-free 3 mm x 3 mm x 0.9 mm, MSL 3 Ordering Information Part No. SE2576L SE2576L-R SE2576L-EK1 Package 16 pin QFN 16 pin QFN N/A Remark Samples Tape & Reel Evaluation kit Functional Block Diagram EN VCC VCC2 Bias & Control RFOUT DET DET RFIN 50 Figure 1: Functional Block Diagram DST-00260 Rev 1.4 Sep-24-2009 1 of 2 SE2576L 2.4 GHz High Power Wireless LAN Power Amplifier Preliminary 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.
