Abstract
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 P-AVG and PAE(AVG) of 6.45 - 12.61 dBm and 5.9 - 16.4% from 25 - 40 GHz, respectively. With a 200 MHz, signal, P-AVG and PAE(AVG) are 5.58 - 11.1 dBm and 4.8 - 13.3%, respectively.
