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.
