A state-of-the-art power amplifier (PA) test platform.

With real-time digital predistortion and envelope tracking, BentoBox attains high linearity and efficiency. It eats other platforms for lunch.


The top panel is the RF Line Up

It's the envelope tracking power amplifier layer.

The bottom panel is AWG & MaXPAL

It generates the signal and does up & down conversion.

The AWG & MaXPAL Panel
