Product Description

The SE2537L 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

SE2537L

offers

extreme

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 partial output match, the power detector with

20dB of dynamic range and a 3.2GHz 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 19.5dBm of linear output power.

For high performance applications, the SP1,2 ports

are available to connect an optional external capacitor

to enhance dynamic EVM performance.

The SE2537L bias control establishes the reference

voltage required for proper operation and allows

enabling and disabling of the power amplifier.
