Product Description

The SE2567L is a 5GHz power amplifier offering high

linear power for wireless LAN applications.

It

incorporates

a

power

detector

for

closed

loop

monitoring and control of the output power.

The SE2567L offers a high level of integration for a

simplified design, providing quicker time to market

and higher application board production yield.

The

device integrates the input match, the inter-stage

match, a temperature compensated, load insensitive

power detector with 15dB of dynamic range and a

3.8GHz notch filter.

Two external components are

required to complete the design.

For wireless LAN applications, the device meets the

requirements

of

IEEE802.11a

and

delivers

approximately 19dBm of linear output power.

The

SE2567L

integrates

the

reference

voltage

generator, allowing for a true CMOS compatible

digital EN (enable) function to turn the power amplifier

on and off.
