Hello, I have designed a branch line coupler on ads. I'm trying to match the ports to 50 ohms.
I would like to ask what is the difference between "Zin" and "impedance" showed on ADS? (i added screenshot)
thank you
Input Impedance ( Zin) should be demonstrated as follows.The other representation shows weird result because Mag(Zin) x cos Arg(Zin) should show the Real Part of Zin but..There is an error or a ADS bug
