Product Description

The SE2582L is a 2.4 GHz power amplifier designed

for use in the 2.4 GHz ISM band for wireless LAN

applications.

The SE2582L is completely integrated including all

RF matching (input, output and interstage) as well as

a high performance power detector for closed loop

monitoring of the output power.

The SE2582L includes a digital enable control for

device on/off control. This functionality allows for a

seamless interface with CMOS transceivers, without

the use of external logic or reference voltages.

The SE2582L temperature compensated power

detector has is highly immune to mismatch at its

output with less than 1.5 dB of variation with a 2:1

mismatch.

The part operates at a low quiescent current making it

ideal for low power applications such as mobile phone

and PDA devices.
