SE2521A60-R

SE2521A60 RangeCharger™ 2.4 GHz Wireless LAN Front End Applications IEEE802.11b DSSS WLAN IEEE802.11g OFDM WLAN Access Points, PCMCIA, PC cards Product Description The SE2521A60 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 SE2521A60 provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antennas in an ultra compact form factor. 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 SE2521A60 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 device also provides a notch filter from 3.2-3.3 GHz prior to the input of the power amplifier. The SE2521A60 is footprint compatible to SiGe’s SE2521A34 and can be placed directly into existing SE2521A34 designs easily providing higher output power solutions Features Pin for pin compatible to SiGe’s SE2521A34 but providing 2 dB extra output power 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

The SE2521A60 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 by SiGe, please refer to: SiGe’s Application Note: “Land Grid Array Module Solder Reflow & Rework Information”, Document Number 69APP-01.
