SE2522L

RangeCharger™ 2.4 GHz Power Amplifier And Power Detector IC

Preliminary Information

Applications

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.

Features

ꢀ

Integrated power detector circuit

High linear output power for IEEE802.11b:

+20dBm, ACPR 1^stlobe –30dBc, 2^ndlobe –50dBc

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.

ꢀ

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

The SE2522L contains a linear analog control (0.1 to

1.6V) for minimizing DC current consumption and

maximizing PAE.
