This presentation discusses the basic concepts and development of multiport interferometer techniques (six-port in particular) and demonstrates their applications in the design of both ultra-wideband and carrier-based transceivers at microwave and millimeter-wave frequencies. Such emerging techniques can be extended to the design of transceivers over terahertz and optical ranges. Various architectures of the multiport circuits are discussed with respect to different applications. Practical implementations under different technological platforms are described with simulated and measured results for QAM and UWB applications. In particular, the equivalence between the multiport junction and mixing circuit is highlighted for direct frequency conversion and translation. It is shown that the proposed multiport technique is very promising and flexible for the low-cost design of microwave and millimeter-wave systems such as software-defined and cognitive radio architectures.
