DIRECT SIX-PORT MODULATOR USING POLYPHASE NETWORKS

摘要

In this article, a novel six-port modulator is proposed and experimentally verified. The six-port modulator circuit is realized by using power dividers/combiners and polyphase networks for the first time. A prototype operating in 2.4-GHz instruments, scientifice and measurement (ISM) band has been fabricated and experimentally verified, to show its performance as vector modulator.
