The present work that conforms this new entry of the blog is an on going task which eventually will not be necessary if the progress of QUCS Studio as a CAD tool continues to develop in the manner that it has being doing until now.
QUCS Studio is really alive and its progression is really awsome. Therefore, eventually, the work that is going to be presented in this new entry will be just a mere theoretical, maybe interesting and meaningless exercise.
One of the things that needs to be improved is the way that the microstrip basic models included in the transmission lines tab deal with the non linear analysis.
Transient analysis and harmonic balance do not work if the schematic that is under simulation contains microstrip line models. This is because this elements are designed to work only with linear analysis like the scattering parameters one.
The elements that are going to be introduced in the document linked in this blog entry try to mitigate this situation until a future version of the software make them useless.
A brief presentation of this work in made in the document that is available in the following link:
Non linear models for Microstrip Basic Elements
The models presented are compiled in this QUCS Studio project that can be downloaded in the following link:
Microstrip Non Linear Models for QUCS Studio
As it has been said in the begining of the entry, this is an on going process, and there is some of the elements that needs to be refined. Any improvement or progress in any of them will be updated. And, of course, any suggestion, correction or any form of cooperation will be really wellcome.
