Abstract

In conventional Multiple-Input Multiple Output (MIMO) systems, each
antenna requires its own Radio Frequency (RF) chain. Since each RF-chain
includes several active components that have to be synchronised, costs
and complexity become restrictive. The outphasing MIMO and the
outphasing precoder architectures are possible approaches to mitigate
this problem. The core of both architectures are Outphasing Elements
(OEs), which are used to form a electronically controllable, passive
antenna feed network. In this paper, these OEs are analysed with respect
to component tolerances. The feasibility of the outphasing concept is
demonstrated by the implementation of a hardware prototype OE. The
performance of this prototype is measured and compared to theoretical
predictions with good agreement.
