A 25-40 GHz Three-Way Power Amplifier with No Load ModulationAchieving Broadband Deep Power Back-Off Efficiency Enhancement
This paper presents a millimeter-wave (mm-Wave)
power amplifier (PA) topology that avoids the trade-off between
bandwidth and load modulation. The proposed topology uses
three PA paths and can achieve efficiency enhancement at power
back-off without load modulation. With a 100 MHz 5G NR FR2
1-CC 64-QAM signal, this PA achieves PAVG and PAEAVG of
6.45 - 12.61 dBm and 5.9 - 16.4% from 25 - 40 GHz, respectively.
With a 200 MHz, signal, PAVG and PAEAVG are 5.58 - 11.1 dBm
and 4.8 - 13.3%, respectively.
