Product Description

The RFPA5552 is a three-stage power amplifier (PA) designed for

Wi-Fi 802.11a/n/ac systems. The compact form factor and

integrated matching minimizes layout area in the application and

greatly reduces the number of external components.

Performance is focused on optimizing the PA for a 3.3V supply

voltage that conserves power consumption while maintaining the

highest linear output power and leading edge throughput.

A key feature is the integration of a logarithmic power detector

which enables power control across the entire power spectrum for

applications which use higher gain antennas or end users wanting

to reduce device calibration time in production.

The RFPA5552 integrates a 5GHz power amplifier (PA), regulator

and power detector into a single device. The device is provided in

4mm x 4mm x 0.9mm, 20-pin QFN package.
