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 µsec.

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.
