This paper presents a CMOS RF power amplifier that employs a digital polar architecture to improve the overall power efficiency when amplifying signals with high linearity requirements. The power ...

Abstract: This article presents the analysis and design of a 26-GHz RF-input load-modulated balanced amplifier (LMBA) using a miniaturized dual-loop (MDL) coupler, implemented in a 0.12- μm gallium ...
