SE2550BL-EK1

SE2550BL 2.4 GHz Low Power Front End Module Preliminary Applications Portable WLAN – Cell phones, PDA’s DSSS 2.4 GHz WLAN (IEEE802.11b) OFDM 2.4 GHz WLAN (IEEE802.11g) Product Description The SE2550BL is a 2.4 GHz front end module designed for use in the 2.4 GHz ISM band for portable wireless LAN applications. The device offers high efficiency at the required output powers to ensure longer battery life for cellphone, PDA and other portable applications. The SE2550BL is highly integrated, allowing for a smaller footprint and simple design. The device includes a power amplifier, digital enable control for device on/off control, T/R Switch, harmonic filter and 50 ohm matching on all I/O. With the digital enable control, the device can be directly connected to a CMOS baseband or transceiver. The SE2550BL 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 Includes: PA, 50 ohm matching, Power detector, harmonic filter and SPDT Switch. 802.11g Output Power + 17 dBm, EVM = 3.0 %, ICC = 125 mA 802.11b Output Power + 19 dBm, ACPR = -40 dBr, ICC = 150 mA 28 dB Gain Robust, selectable slope, power detector with ~1.5 dB variation over 2:1 mismatch Integrated power amplifier enable pin (VEN) Single supply voltage: 2.7 V to 3.6 V Lead free and RoHs compliant Small, lead free package, 18 pin 4 mm x 4.5 mm x 0.6 mm QFN, MSL3 Ordering Information Type SE2550BL SE2550BL-R SE2550BL-EK1 Package 18-QFN 18-QFN Evaluation Kit Remark Samples Tape and Reel Standard Functional Block Diagram V CC0 V EN V CC3 C1 C2 Bias Generator RF I N 50 Ohm Match SPDT Stage 1 Stage 2 Stage 3 Filtering ANT Detector (with Switch) RX O U T V CC1 V CC2 Slope SEL V DET OUT Figure 1: SE2550BL Functional Block Diagram 65-DST-01 Rev 1.3 May-26-2009 QA040506 1 of 2 SE2550BL 2.4 GHz Low Power Front End Module 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.
