Modeling Filters with AADE software

I am looking to build some modular bandpass and lowpass filters for some projects.

Here is an example of a 40m Butterworth bandpass filter

I am using the AADE software for the modeling.

  • I would like to design some filters that use common value components.
  • Bandpass
  • Lowpass
  • Make a small modular board with header pins
The idea is that you could plug the modular card into a breadboard or pcb with header pins. There are a lot of times when I am prototyping that I would like to have some filters on hand and a modular approach would be incredibly helpful.

So tonight I am spent a little bit of time bonding with the software looking at some design options and then comparing the part values with standard parts that are available at Mouser and/or Digikey.

Part of the magic is converting the parts to standard sizes and then rerunning the model to see if the parameters are still close enough that the design remains valid.
