Is there a way to simulate s-param changing tapping point of M-Line in ADS?
I've tried with two M-Lines and putting terminal in between but wondered if there is a better way to simulate the circuit.
Thanks in advance.
 

What are you talking about? Show a screenshot, please.

this is what I did and I was wondering if I could get the same simulation result by using only one microstrip line
 

I guess he means MLIN and searches for MTEE, but the question is unclear indeed.


Use correct terminology

No, two lines is correct.

If your feed from the port is microstrip also, add an MTEE element between the MLINs. That MTEE models the parasitics at the interconnection.

If you want to move the tapping point, use a variable, e.g. "offset" that defaults to 0. Set TL1 length to 3mm - offset and TL2 length to 7.1mm + offset. You can then use parameter sweep or tuning to change that offset variable.
 

Use correct terminology.
There is no simulator whose name is “ADS”.
“ADS” is a name of design framework.

”ADSsim” is a correct terminology.

Executable command of simulator is “adssim”.
Previously it was a “hpeesofsim”.
However we can still use “hpeesofsim” as well as “adssim”.

We use followings to specify syntax in mixed format netlist.
Code:
simulator lang=spectre
simulator lang=spice
simulator lang=adssim

The term ADSsim has been replaced in ADS documentation since ADS 2017.
The correct terminology used in ADS documentation is "Analog/RF simulation".
