Hi everyone --
I have designed a filter using discrete components in ADS and I am now trying to design the microstrip lines to interconnect all of the parts. I've used Linecalc to determine the width needed for a 50 ohm microstrip line (given my particular substrate). Now I am sort of lost. I don't want to just throw microstrip lines in the circuit, I want to use a little sense, heh. Are there any guidelines to follow? I am really new to the subject so I kind of tried to position them in a way that should work. I don't want to get any coupling effects (from lines being too close together)...etc..
Also when I generate the layout from the schematic using ADS it looks like a big jumbled mess. This is partly because some of my components don't have a physical size added to them. Is there a way to add these dimensions to the components (say using the Coilcraft ADS library for their inductors), or do I have to space the lines perfectly in the layout section. If I did that, could I run simulations with momentum?
If any of you have any tutorials I would really appreciate it. I've searched all over and I can't find anything that relates to microstrip interconnect design with discrete components.
Thanks,
Sam
