| SE2568U 2.4 GHz High Efficiency Wireless LAN PA Preliminary Applications IEEE802.11b DSSS WLAN IEEE802.11g OFDM WLAN Embedded, SiP modules Product Description The SE2568U is a complete 802.11 b/g WLAN discrete power amplifier. The device provides all the functionality of the power amplifier, power detector, filter, associated input, inter-stage and output matching in an ultra compact 2mm x 2mm x 0.5mm form factor. The SE2568U is designed for ease of use, with all the critical input and output matching integrated. The SE2568U includes a transmitter power detector with 20 dB of dynamic range and a digital Enable for power on/off control. Harmonic filters and an input 3.2GHz LO rejection filter are integrated on-chip. The power ramp rise/fall time is 0.7 s typical. Features Dual Mode IEEE802.11b & IEEE802.11g Integrated PA, digital bias control, 50 input and output match, 3.2GHz TX Filter. Integrated harmonic filter. Integrated load insensitive Power Detector, with <1dB error at 2:1 mismatch 20 dBm Output Power, 802.11b, 11 Mbps, ACPR <-30 dBc 18dBm @ 3.0 % EVM, 802.11g, 54 Mbps 2.3 V to 4.8 V direct to battery supply Lead free, Halogen free, ROHS compliant , 2 x2x0.5 mm QFN package, MSL 1 Ordering Information Part No. SE2568U SE2568U-R SE2568U-EK1 Package 8 pin QFN 8 pin QFN N/A Remark Samples Tape and Reel Evaluation kit Functional Block Diagram EN VCC VCC2 Bias Circuitry 50ohm Match & harmonic Filter Detector RF IN 50ohm Match 3.2GHz Filter RF Out Pdet Figure 1: Functional Block Diagram DST-00190 Rev 2.0 Sep-29-2009 Page 1 of 2 SE2568U 2.4 GHz High Efficiency Wireless LAN PA 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.
