Thanks a lot for this very useful project. Hope it will come at the end of its roadmap ! I'm working in a french laboratory, the "Institut des Sciences du Mouvement", in Marseille, France. I'm using QUCS for teaching. I'm writing a reference for QUCS in PLUME, a french project to promote useful, economic and controlled software (https://www.projet-plume.org/) but I do not have any information on QUCS usage.
Could you please write where QUCS is officially used ? In which company, which university or research group ? In other words : you, all the people who are using QUCS, who are you ? where are you working ?
Thanks a lot for your answers :-)
Personally I've rarely used Qucs as a student; more like a hobby. However I've used Qucs for learning purposes before even knowing it existed: its documentation (which I found on Google) is quite nice and was rather helpful when I was learning the Modified Nodal Analysis method.
I think the educational potential of this program is underrated: it's free, unrestricted, translated to many languages, has an extended documentation, multi-platform, incredibly easy to use… not very powerful but probably just what a student needs. One of its weak points is its slow development, though.
Work in a small company (<10 employee) which is doing RF amplifier (1-3Ghz/10W-500W) for telecommunications. Trying Qucs since few month for the transistor matching. Hope that it will be a good alternative to ADS (which is really hard to buy).
Anything better than a Smith Chart software is welcome^^
Except ADS and perhaps Genesys (which I never used), both from KT, I think you cannot find better than Qucs for the purpose you cited (transistor matching and Smith charts).
I think the weakness are the transient simulator and the very pernickety harmonic balance simulator. Hard for nonlinear RF devices designers... Well, it's a free software with non-remunerated programmers who already work quite hard on GitHub.
Personnally, I use Qucs as a hobby, and by the past, for studies purposes. By the way, it's hard to find a teacher that is not obsessed by Spice-based softwares!
