Abstract
This article presents a wideband energy-efficient
transmitter (TX) for 5G mm-wave phased-array systems.
It features an advanced double-quadrature direct upconverter
(DQ-DUC) to improve its in-band linearity and spectral purity.
The proposed TX architecture incorporates an efficiency-
enhanced balanced power amplifier (EEBPA) that mitigates
VSWR fluctuations in phased-array systems while enhancing
efficiency at power back-off (PBO). The EEBPA comprises
two identical series-Doherty power amplifiers (PAs
