| SE2537L 5 GHz Power Amplifier with Power Detector Applications DSSS 5 GHz WLAN (IEEE802.11a) Access Points, PCMCIA, PC cards Product Description The SE2537L is a 5GHz power amplifier offering high linear power for wireless LAN applications. It incorporates a power detector for closed loop monitoring and control of the output power. The SE2537L offers extreme integration for a simplified design, providing quicker time to market and higher application board production yield. The device integrates the input match, the inter-stage match, a partial output match, the power detector with 20dB of dynamic range and a 3.2GHz notch filter. Two external components are required to complete the design. For wireless LAN applications, the device meets the requirements of IEEE802.11a and delivers approximately 19.5dBm of linear output power. For high performance applications, the SP1,2 ports are available to connect an optional external capacitor to enhance dynamic EVM performance. Remark Samples Tape and Reel Standard The SE2537L bias control establishes the reference voltage required for proper operation and allows enabling and disabling of the power amplifier. Features High output power amplifier 19.5dBm Only 1 external component required Integrated power amplifier enable pin (VEN) Buffered, temperature compensated power detector 3% EVM, @19.5dBm, 64 QAM, 54 Mbps 30 dB Gain Lead Free, Halogen Free and RoHS compliant package 16 pin 3 mm x 3 mm x 0.9 mm QFN Ordering Information Part Number SE2537L SE2537L-R SE2537L-EK1 Package 16 Pin QFN 16 Pin QFN Evaluation Kit Functional Block Diagram VEN Bias RFIN Input Match Interstage Match Interstage Match Output Match RFOut Detector VCC1 VCC2 VCC3 Vdet Figure 1: Functional Block Diagram DST-00097 Rev 1.4 Jul-07-2009 Confidential 1 of 2 SE2537L 5 GHz Power Amplifier with Power Detector 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.
