1 / 8 page  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 Features Integrated power detector circuit High linear output power for IEEE802.11b: +20dBm, ACPR 1 st lobe –30dBc, 2nd lobe –50dBc Low current consumption: 110mA at 3.3V High saturated output power for cordless telephone applications: +23dBm, 140mA at 3.6V Single supply voltage: 2.7 to 3.6V Wide Temperature range: -40°C to +85°C Integrated linear analog control for DC current and output power management Small plastic package: 8 Pin LPCC Ordering Information Type Package Remark SE2522L 8 Pin LPCC Samples SE2522L-R 8 Pin LPCC Shipped in Tape & Reel SE2522L-EK1 Evaluation Kit 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. This device is capable of operating at a duty cycle of 100 percent.
