Hello,
I saw a previous thread where it ended on a question that I would like to know the answer to: https://www.edaboard.com/threads/component-selection-for-rf-circuits.280238/ . It ends wondering when you should switch to a smaller component. The general consensus seems to be always chose the smallest component that can handle the power. This minimizes size and parasitic effects, but is there a general rule? At 20 GHz a 0805 would cause a lot more effects then a 0201, is there a general chart? Or just always select the smallest that can handle power?
Thanks,
