1 / 2 page  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) 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 Package Remark SE2550BL 18-QFN Samples SE2550BL-R 18-QFN Tape and Reel SE2550BL-EK1 Evaluation Kit Standard 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.
