How to design a L Band Oscillator with QUCS Studio and Free CAD

The same way that I described in a previous entry how to proceed to design a L band amplifier using as designing tool QUCS Studio, this time I will present a tutorial about designing a L band oscillator using the same environment. 

The most relevant part to make the difference compared to the previous mentioned tutorial is that, this time, non linear analysis are the essential part of the simulations.  

This time, in order to get an accurate analysis of the circuit response, another CAD tool is used to design the layout of the oscillator. This time, is Free CAD. The outcome is really cool. The 3D views of the circuit give to the design almost a professional touch.

The tutorial can be downloaded from here:
