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.
