Flexradio Aurora AU-520M 500W

The world’s first truly integrated 500W SDR transmitter

the Aurora Series delivers exceptional RF performance in a radically compact form
factor—leveraging cutting-edge high-efficiency technology that produces more power with less weight, lower heat,
and dramatically reduced power input requirements.

At the heart of Aurora is a revolutionary 500W transmitter module that achieves up to 90% efficiency—a dramatic
leap over conventional MOSFET and LDMOS designs, which typically operate at 40–60%. The result: less heat
to dissipate, a smaller heatsink, and a much lighter radio.

The entire 500W transmitter fits in the same physical envelope as traditional 100W PA systems and runs cool
enough to share the existing FLEX-8000 heatsink footprint.

This level of integration means operators no longer need to carry or connect external power amplifiers, tuners,
or heavy AC/DC power supplies.

The Aurora Series includes everything needed inside the chassis.
