Product Description

The SE2590L is a 2.4 GHz power amplifier designed

for use in the 2.4 GHz ISM band for wireless LAN

applications.

The

device

incorporates

a

power

detector for closed loop monitoring of the output

power.

The SE2590L includes a digital enable control for

device on/off control.

The
