Modern society has shown a large demand for ubiquitous and wireless connectivity, information transmission with high data rates, and precise sensors for any kind of physical dimension. Nevertheless, the frequency spectrum is limited and bandwidth restricted by regulatory issues. Initially, before the cost of this technology becomes reasonable, alternative hybrid circuit concepts are needed as a door opener for mass-market applications. For this purpose, an old frontend concept is getting increased support, leading to a constant growth of an originally small, but worldwide, community: multiport technology. The multiport structure is basically a passive circuit comprising several couplers interconnected by transmission lines and phase shifters. Its specific architecture and design are strongly related to the target application and the aimed operating frequency
