Abstract
This article presents a wideband series-Doherty
power amplifier (SDPA) for millimeter-wave (mm-wave) fifth-
generation (5G) applications. I t features a compact two-step
impedance inverting-based series-Doherty power combiner
that provides broadband close-to-perfect power back-off
(PBO) efficiency enhancement. The amplitude-to-amplitude
(AM–AM)/amplitude-to-phase (AM–PM) performance of the
load-modulated Doherty power amplifier for broadband oper-
ation is analyzed. We also devise a post-silicon int
