Product Description

The SE2523BU is a 2.4 GHz power amplifier

designed for use in the 2.4 GHz ISM band for wireless

LAN

applications.

The

device

incorporates

two

selectable power detectors for closed loop monitoring

of the output power.

The SE2523BU includes a digital enable control for

device on/off control.

The SE2523BU temperature compensated power

detector has two selectable power detectors slopes,

positive and negative.

This allows easy use with

multiple chipsets. The detector is also highly immune

to mismatch at its output with less than 1.5 dB of

variation with a 2:1 mismatch.
