On Differences Between Transmission Line-based Wave Digital Models of Gysel Power Dividers

The paper proposes different designs of the wave digital model (WDM) of three-port microwave device. By adopting transmission line (TL)-based wave digital approach to design the model, the wave-flow equivalents to TLs and circuit elements, as well as interconnection networks are required. As a case study, two different Gysel power dividers are modeled and their differently generated TL-based WDMs are compared regarding magnitude and phase responses.
