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.
