Abstract
This article presents a millimeter-wave (mm-wave)
Doherty-like load modulated balanced amplifier (LMBA) for
high-speed wireless communication in a 28-nm bulk CMOS
process. The presented architecture is based on a load modulation
technique that injects an auxiliary signal into the isolation port
a9 0
◦ power-combining hybrid coupler at the output stage. The
injected signal thereby modulates the load impedance at the
balanced ports that is seen by the two main power amplifiers
(PAs). In contrast to
