SE2529L
RangeCharger™ 2.4GHz Power Amplifier
Applications
DSSS 2.4GHz WLAN (IEEE 802.11b) OFDM 2.4GHz WLAN (IEEE 802.11g) Access Points, PCMCIA, PC cards 2.4GHz cordless telephones
Product Description
The SE2529L is a 2.4GHz, Silicon Germanium power amplifier designed for use in the 2.4GHz ISM band for wireless LAN and cordless telephone applications. For wireless LAN applications, the device meets the system requirements of IEEE802.11g and delivers approximately +19dBm, at an EVM of 2.5%, while achieving an adjacent channel power of better than – 26dBc @ 11MHz offset. The SE2529L meets this performance and output power while adhering to the FCC 15.209 restricted band requirements. For IEEE802.11b, the SE2529L delivers approximately +23dBm @ ACPR = -32dBc. The SE2529L typically achieves harmonic performance of -65dBc with the recommended discrete integrated output match and low pass filter, thus not requiring an expensive and larger band pass filter.
Features
Delivers industry leading output power: +19dBm, 802.11g, 54 Mbps, EVM = 2.5% +23dBm, 802.11b, ACPR < -32dBc +25dBm CW P1dB at 3.3V Superior harmonic performance, No band pass filter required allowing for a lower BOM 31dB Gain Exceptional temperature stability Small plastic package, 12 pin QFN
