DOI: 10.1109/jssc.2020.2970708
Abstract: Designing Doherty power amplifiers (PAs) at high millimeter-wave (mm-Wave) range remains a major challenge because most Doherty combiners at this frequency band are inefficient. To resolve this bottleneck, we analyze balun response under load variation… read more here.
