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 and subsequently propose the Doherty
PA architecture with impedance inverting and scaling baluns
that perform active load modulation on differential PAs and
delivers combined power to a single-ended load. At the PA
output/input stage, instead of uti
