Re: Question on test scheme design for 4-port microstrip cir
Dear all,
I designed a small four-port microstrip circuit (device under test), and obtained the simulation results. Since this 4-port microstrip circuit is very small, it does not have enough space for SMA connector mounting. Now I want (but I have no idea) to design a proper test scheme for purpose of the SMA-connector measurement of S parameters of this tiny four-port DUT by using four-port vector network analyzer. I really appreciate whatever help you could offer me on the test scheme design.
Thanks a lot.
Sincerely yours,
Kevin

By reading the de-embedding method with coupled line TRL calibration using four-port vector network analyzer, I designed a test scheme below. Any suggestions are greatly welcome. Thank you.
