With a 2-port VNA, I would like to characterize the performance of a single coax connector, specifically to obtain VSWR.
The specific situation is an SMA connector at the end of a short section of semi-rigid 50 ohm coax that has no connector on the other end.
The two techniques I can think of are:
Add the same connector to the coax, creating a short double ended cable, and using the known electrical length, obtain the S parameters for one connector. I do not know the exact formula.
Try to terminate the coax with a 50 ohm load. I think that soldering a resistor would not work properly at these frequencies (>9 GHz).
Are there techniques I am missing?
