DATA SHEET SE2521A80: 2.4 GHz Wireless LAN Front-End Preliminary Applications Product Description The SE2521A80 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 SE2521A80 provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antennas in an ultra compact form factor. IEEE802.11b DSSS WLAN IEEE802.11g OFDM WLAN Access Points, PCMCIA, PC cards Features Dual Mode IEEE802.11b & IEEE802.11g All RF ports matched to 50 Ω Integrated PA, TX Filter, DPDT T/R and Diversity switches Integrated Power Detector 20 dBm @ 3.0 % EVM, 802.11g, 54 Mbits 20 dBm, 802.11b, ACPR = -37 dBr, 11 Mbits Single supply voltage: 3.3 V ± 10 % Small lead free package, 8 mm x 7 mm x 1.2 mm, MSL 3 Designed for ease of use, all RF ports are matched to 50 Ω to simplify PCB layout and the interface to the transceiver RFIC. The SE2521A80 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 1 μsec typical. The SE2521A80 is pin for pin compatible to Skyworks’ SE2521A34 for easy transition of medium power designs to higher power designs. Ordering Information The device also provides a notch filter from 3.2-3.3 GHz prior to the input of the power amplifier.

The pads on the Skyworks RF modules are plated with gold over nickel, with a gold thickness of nominally 0.75 um. The modules can be reflowed onto FR4 based material using eutectic SnPb or common tin based Pb free solder pastes. 5 4 3 2 1 6 1 24 GND GND GND GND 3 4 GND GND 5 6 GND GND 7 23 GND GND GND GND GND GND 8 9 GND 7 GND GND GND GND GND GND 8 22 9 21 21 10 GND 23 22 20 GND 2 24 20 10 GND GND GND GND GND 19 11 19 11 GND GND GND GND GND GND 13 14 15 16 17 18 12 GND GND GND 16 15 14 GND 18 12 17 13 TOP SIDE NOTES : GROUND PAD DETAIL SIGNAL PAD DETAIL BOTTOM SIDE Figure 7: SE2521A80 Package Diagram Package Handling Information Because of its sensitivity to moisture absorption, instructions on the shipping container label must be followed regarding exposure to moisture after the container seal is broken, otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SE2521A80 is capable of withstanding a Pb free solder reflow. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. If the part is manually attached, precaution should be taken to insure that the device is not subjected to temperatures above its rated peak temperature for an extended period of time. For details on both attachment techniques, precautions, and handling procedures recommended, please refer to: “Land Grid Array Module Solder Reflow & Rework Information”, Document Number QAD-00046 “Handling, Packing, Shipping and Use of Moisture Sensitive LGA”, Document Number QAD-00047 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 202417A • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • September 25, 2012 10 DATA SHEET SE2521A80: 2.4 GHz Wireless LAN Front-End Preliminary Recommended PCB Footprint Figure 8 shows the recommended PCB footprint for the SE2521A80.
