A 10 W GaN/Si Doherty Power Amplifier Designed for 15 GHz 6G Band with 8 dB Backoff Efficiency
Paper i proceeding, 2025
This paper presents the design and implementation of a 10W GaN-on-Si Doherty Power Amplifier (DPA) for operation in the 15 GHz 6G band. The DPA was fabricated using Infineon's RF GaN-on-Si MMIC process. An experimental (simulation) result shows a peak PAE of 30-37%, and 22-27% PAE at 8 dB backoff, 10dB gain, and 2 GHz bandwidth. Thermally limited CW measurements confirmed high back-off efficiency with 24% PAE at 29 dBm output power at 14 GHz.
