Design Tools
1)Phase Shifting Impedance Matching Network 2.1
Using this software, one can design an impedance-matching network with a desired phase shift. There are different types of topologies available: Lumped, Distributed and Mixed. The sub-topologies are T, Pi, L and stepped. Frequency-dependent load can be simulated using s1p file (touchstone 2.0). Broadband matching networks can be designed using multisection matching networks.
2) Microwave Filter Design Kit
This is a small toolkit for developing and analysing Filters for low as well mmWave frequency applications. The simple design and GUI require minimum effort to develop the desired filter. Furthermore, various implementation options are available for mmWave filters and the response of all these implementations is readily available through Scattering parameters.
3) Quadrature/Non-Quadrature Branch Line Coupler with Equal/Unequal Power Division
This work provides a computer-aided design solution for non-quadrature (or quadrature) branch-line couplers with unequal (or equal) power divisions. 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 Y-matrix method. The scattering parameters analysis of the designed coupler is also based on the Y-matrix method.
4) Single/ Dual band Rat-race Coupler and Gysel Power Divider with unequal power division ratio
6)Impedance Transforming RRC and BLC
This work provides a computer-aided design (CAD) solution for impedance transforming ratio-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.
7) Nonuniform Transmission Line Analyzer
Transmission line Impedance Tapers are critical components in signal transmission systems, aiding in impedance matching and minimizing signal reflections. Accurate simulations are essential for analyzing the electrical performance of these tapers. This research work presents a CAD tool developed using Python that enables the simulation of different transmission line tapers using analytical and numerical methods. The CAD tool provides engineers and researchers with an intuitive graphical interface to visualize and analyze the behaviour of transmission line tapers effectively.
