Archivio Istituzionale della RicercaThis paper presents the design and characterization of an SLMBA targeting 10-dB back-off efficiency enhancement in the N78 (3.3-3.8 GHz) 5G band. The design aims at minimizing complexity by adopting identical transistors in all branches and the same drain supply voltage. The prototype delivers more than 44dBm saturated output power while maintaining efficiency higher than 56% and 34% at saturation and 10 dB back-off, respectively. This confirms the validity of the approach in providing performance in line with the current state of the art.

Abstract
This paper presents the design and characterization of an SLMBA targeting 10-dB back-off efficiency enhancement in the N78 (3.3-3.8 GHz) 5G band. The design aims at minimizing complexity by adopting identical transistors in all branches and the same drain supply voltage. The prototype delivers more than 44dBm saturated output power while maintaining efficiency higher than 56% and 34% at saturation and 10 dB back-off, respectively. This confirms the validity of the approach in providing performance in line with the current state of the art.
