SE2559L20 2.4 GHz High Efficiency Wireless LAN Front End Preliminary Applications Product Description IEEE802.11b DSSS WLAN IEEE802.11g OFDM WLAN Access Points, PCMCIA, PC cards Features Dual Mode IEEE802.11b & IEEE802.11g Integrated PA, TX Filter, DPDT T/R and Diversity switches Integrated Negative Slope Power Detector 21 dBm Output Power, 802.11b, 11 Mbits, ACPR <-30 dBc 18 dBm @ 3.0 % EVM, 802.11g, 54 Mbits Single supply voltage: 3.3 V ± 10 % Lead free, halogen free and RoHS compliant Small lead free, plated package, 4 mm x 5 mm x 0.9 mm, MSL 1 The SE2559L20 is a complete 802.11 b/g WLAN RF front-end module providing all the functionality of the power amplifier, power detector, T/R switch, diversity switch and associated matching. The SE2559L20 provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antennas in an ultra compact form factor. The SE2559L20 is designed for ease of use, with all the critical matching and harmonic filtering integrated, offering a simple 50 Ω interface to the antenna. The SE2559L20 also includes a transmitter power detector with 20 dB of dynamic range and a digital enable control for transmitter power ramp on/off control. The power ramp rise/fall time is 0.5 μs typical. The device also provides a 3.2–3.3 GHz notch filter prior to the input of the power amplifier.
