SE2522L-EK1

SE2522L RangeCharger™ 2.4 GHz Power Amplifier And Power Detector IC Preliminary Information Applications IEEE 802.11b DSSS radios, Wireless LAN 2.4GHz cordless phones, ISM radios Product Description The SE2522L is a power amplifier IC designed for the 2.4GHz ISM band and compliant with the IEEE 802.11b WLAN standard. It typically provides +20dBm linear output power requiring only 110mA at 3.3V. It can also be utilized in 2.4GHz cordless telephone applications where it typically provides +23dBm saturated output power at 3.6V. The SE2522 includes an integrated power detector circuit for closed loop monitoring of output power. It has an input power range of 15dB with an accuracy of ±1.0dB. An accurate automatic level control function can easily be implemented using this power detector circuit. The SE2522L contains a linear analog control (0.1 to 1.6V) for minimizing DC current consumption and maximizing PAE. The SE2522L includes a digital enable control for device on/off control where ramping is typically 1 µsec.
