| SE2523BU 2.4 GHz Power Amplifier with Power Detector Preliminary Applications DSSS 2.4 GHz WLAN (IEEE802.11b) OFDM 2.4 GHz WLAN (IEEE802.11g) Portable and Battery WLAN Applications Access Points, PCMCIA, PC cards Product Description The SE2523BU is a 2.4 GHz power amplifier designed for use in the 2.4 GHz ISM band for wireless LAN applications. The device incorporates two selectable power detectors for closed loop monitoring of the output power. The SE2523BU includes a digital enable control for device on/off control. The SE2523BU temperature compensated power detector has two selectable power detectors slopes, positive and negative. This allows easy use with multiple chipsets. The detector is also highly immune to mismatch at its output with less than 1.5 dB of variation with a 2:1 mismatch. Features Single 3.3 V Supply Operation 18.5 dBm, EVM = 3 %, 802.11g, OFDM 54 Mbps 23 dBm, ACPR < -32 dBc, 802.11b 32 dB Gain Selectable Power Detector Slope for use with multiple chipsets (Negative and Positive) Integrated power amplifier enable pin (VEN) Lead Free and RoHS Compliant Ultra thin package: 0.5 mm Small package, 16 pin 3 mm x 3 mm x 0.5 mm QFN Ordering Information Part Number SE2523BU SE2523BU-R SE2523BU-EK1 Package 16 Pin QFN 16 Pin QFN Evaluation Kit Remark Samples Tape and Reel Standard Functional Block Diagram VCC0 VEN Bias Generator IN Stage 1 Stage 2 Stage 3 OUT/VCC3 Detector (with Switch) V CC1 V CC2 SLOPE SEL V DET OUT Figure 1: Functional Block Diagram 192-DST-01 Rev 1.3 May-26-2009 QA041206 1 of 2 SE2523BU 2.4 GHz Power Amplifier with Power Detector 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.
