De-embedding of cable with connectors in ADS for S-parameter

Hi,

I am new to de-embedding. I got s-parameter of a Twinax cable and same connector at the two ends of the cable from the manufacturer. They won't provide any s-parameter file only with the Twinax cable without connector. But for specific reason I need the s-parameter file only for cable w/o connectors. I found out de-embedding technique yesterday. Most of the de-embedding techniques as I found are removing the fixture which is in my case the connectors. But the s-parameter I got includes connector+cable. How to de-embed in this case in ADS?

There is de-embed component in ADS which takes s-parameter. What type of data should I put in the de-embed component?

It is difficult to answer without knowing what your problem and goal is.

If the connector is good, it will just add a phase delay. How much ... depends on the ref plane that you choose.

Thanks @,

My goal is to extract the s-parameter of only the cable without the connectors from the provided s-parameter (connector+cable+connector). The connector is good but for specific simulation and verification I need to extract the s-parameter of the cable only...

That is what you wrote before, but not enough to answer your question. De-embedding requires information on the connector, you can't de-embed without knowing the connector's response. Good luck!

Somehow I got the connector s-parameter. But I got 20 port s-parameter file (10 differential) of the connector as it supports 10 differential connection. the cable with same connector s-parameter file is differential (4-port). Can I use the s-parameter of the 20-port connector for de-embedding (maybe, somehow enabling for 1 differential port in and out for the 20-port connector)?

I read a lot of literature, but the de-embedding block is still vague to me. I got what the function does. But is the de-embedding block the block of the connectors for my case which I want to cut-out from the cable?
