microstrip matching
Hi all,
I have completed a design for a planar broadband microstrip matching network and would like to simulate it before rebuilding it. My load is highly capacitive and nonuniform throughout its 10% fractional bandwidth, although not varying drastically within the band. I wanted to match this to 50Ω and have successfully done so, at least, only in theory.
Previously, I used ADS schematic and I used MTEE and MCROS parts whenever necessary to include the effects of a bend, or such, in my circuit.
However, after optimizing and building it on FR4, the results are way off and I thought that (a) I need to use ADS momentum or another software, which I'm not sure how to do most especially since I need the S1P file of the load as reference so that it could probably perform simulation and optimization/tuning from there Besides momentum, anything else you would recommend, especially ones that feature the 'data items' feature of ADS? (b) I'd have to fabricate everything one at a time and try to return everything from there (which I honestly, would say, is more tedious and would like to avoid if there's any other alternative. So far, it seems like there isn't (from colleagues/boss) and this is why I am here asking for help/other suggestions).
My network is composed of lines that have different Z0 in order to make it work. I've applied a few concepts from filter design such as Kurokawa's transformation.
Please help.
Thanks in advance
