I draw the schematics on ADS: trace widths are 0.15 mm and lengths are about 1.1 mm from CC2650 to the balanced ports; trace width is 0.6 mm and length is about 12.1 mm from balanced port of the balun to the SMA connector.
However, S 1,1 plot shows a very bad impedance matching (I use S parameters of balun supplied by Murata)
Why don't I see a matched circuit? Do I do anything wrong in the simulation or does impedance match of the EVM (SMA connector) not have a good impedance match?
In case I simulate (draw the schematics) it wrong, Is there any guideline (or any document) how the simulation should be done? If there is no such document, would it be possible to briefly describe how the simulation should be done? Or is it possible to send me schematics or simulation file for CC2650em-murabal-rd's impedance matching part.
I would highly appreciate for the answers.
P.S I am aware that I didn't define the angled traces to draw it quick
