| SE2522BL RangeChargerTM 2.4GHz +23 dBm Power Amplifier Preliminary Information Applications DSSS 2.4GHz WLAN (IEEE802.11b) OFDM 2.4GHz WLAN (IEEE802.11g) Access Points, PCMCIA, PC Cards 2.4GHz Cordless Telephones Product Description The SE2522BL is a 2.4GHz power amplifier. The device is designed for use in the 2.4GHz ISM band for wireless LAN and cordless telephone applications. It incorporates a power detector for closed loop monitoring of output power. For wireless LAN applications, the device meets the requirements of IEEE802.11b and delivers approximately +23dBm @ ACPR = -30dBc. In IEEE802.11g applications the PA delivers approximately 16dBm. For cordless telephone applications, the SE2522BL delivers up to +25dBm saturated output power at 3.3V. The SE2522BL includes a linear analog control (0.1 to 1.6V) for minimizing DC current consumption and maximizing PAE. The SE2522BL contains a digital enable for device on/off control, ramping is typical 1 sec. The SE2522BL contains an integrated power detector with an input power range of 15dB, and an accuracy of 1.0dB. An accurate automatic level control function can easily be implemented using this detector circuit.
