Product Description

The SE5003L is a 5GHz power amplifier offering high

linear power for wireless LAN applications.

The

SE5003L incorporates a power detector for closed

loop monitoring and control of the output power.

The SE5003L offers high 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, the

output match, the power detector with 15dB of

dynamic range and a 3.8GHz notch filter.

Only 6

external

decoupling

capacitors

are

required

to

complete the design.

For wireless LAN applications, the device meets the

requirements of IEEE802.11a & 802.11n, and delivers

approximately 23dBm of linear output power at 5V.

The

SE5003L

integrates

the

reference

voltage

generator. A 2.85V reference voltage on VREF is all

that is required to enable or disable the power

amplifier.
