Abstract :
A lossless multi-way power combining and outphasing system has been recently proposed which offers major performance advantages over conventional approaches such as Chireix power combining. This paper presents a new outphasing control strategy for the proposed system that enables output power control through effective load modulation of the power amplifiers while minimizing susceptive variations in loading. Moreover, a simple methodology for designing the combiner is introduced.
