Base details
Website, pricing, platforms and company facts side by side.
Open Source QUCS is free to use, and its source code is openly available, allowing for customization and community-driven improvements.
Comprehensive Simulation QUCS supports a wide range of simulation types, including DC, AC, S-parameter, harmonic balance, and more, making it versatile for various applications.
Cross-Platform Compatibility The software runs on multiple operating systems such as Windows, Linux, and macOS, making it accessible to a broad audience.
Wide Component Library QUCS offers an extensive library of components that can be used in circuit design, which simplifies the process of creating and simulating circuits.
User Community Support The community around QUCS can provide support, share tips, and contribute to the software’s development.
Detailed Documentation QUCS offers comprehensive documentation, tutorials, and examples to assist users in understanding and using the software effectively.
Possible disadvantages
Steep Learning Curve Beginners may find the software complex and challenging to master due to its extensive features and functionalities.
Limited Advanced Features Compared to commercial alternatives, QUCS may lack some advanced features and tools that are available in paid software.
User Interface The graphical user interface of QUCS may appear outdated and less intuitive compared to modern, commercial simulation tools.
Performance Issues For very large and complex circuits, the simulation performance might suffer, and the software could be slower than some commercial solutions.
Inconsistent Updates Being a community-driven open-source project, updates and new features may be released inconsistently or less frequently.
Documentation Gaps While there is detailed documentation available, certain advanced features or troubleshooting tips might not be well-covered or updated.
Likely focused on expense splitting Based on the name, Splitaha appears to be a bill or expense-splitting tool. I could not access or verify the site, so confirm this on splitaha.com. If it is, a tool built for one purpose is usually simpler than a general finance app.
Potential convenience for group costs Expense-splitting apps generally replace manual spreadsheets and chat arithmetic for trips, roommates and shared meals. Check whether Splitaha offers features such as automatic balance calculation or simplified debts.
Possible low barrier to entry Many apps in this category have free tiers or need no complicated setup. I have not verified Splitaha's pricing or onboarding, so check them directly.
Possible disadvantages
Unverified information I could not browse the site or find reliable details about Splitaha, so any feature claims here are assumptions. Check the site itself before relying on them.
Limited track record or reviews I found no established user reviews, so I cannot confirm its reliability, popularity or support quality. Look for independent reviews and app store ratings.
Unknown data privacy and security Apps that handle shared financial details should state clearly how they store and protect data. Review Splitaha's privacy policy and security practices before entering sensitive information.
Unknown payment and integration support It is unclear whether Splitaha supports settling up through payment services, multiple currencies or exports. Established competitors such as Splitwise offer some of these, so compare features before committing.

How do dual-directional couplers behave with a mismatched load?
If you can get s parameter model you can use that. There are also generic transformer and coupled line models so long as you've got a way of characterising it you should be able to model it. https://sourceforge.net/projects/qucs/.
