Impedance Transforming RRC and BLC
Description
This work provides a computer-aided design (CAD) solution for impedance transforming rat-race and branch-line couplers (RRC and BLC). The design application provides three topological choices: lumped, distributed and mixed (a combination of lumped and distributed). Each topology mainly has T and $\Pi$ sub-topologies. In addition, transmission line and stepped line topologies are included in distributed topology. The underlying design algorithms are developed using the generalized S-matrix of BLC and RRC [1] and the Y-matrix method [2]. The scattering parameters analysis of the designed coupler is also based on the Y-matrix method.
The application is downloadable from Zenodo. It is free software and is available under Creative Commons Attribution 4.0 International. The software is developed using Python and Python Modules. After downloading the zip file Impedance_Transforming_RRC_BLC, the user needs to extract the zip file and double-click on the exe file main.exe to open the application window. The detailed background theory will be available soon.
