Homemade Low-Pass Filter
I made this filter for one of my friend. Unfortunately, we were below time pressure so I couldn't tune the S11 parameters properly. On the other hand, the cutoff frequency was correct and I am very happy that it worked well for his application. Take a look at the following images.
If you design a similar filter, make sure that the legs of the capacitors are as short as possible. It will help you to get better performance.
