HI!!
I have implemented the '3-port circulator' example provided with the rf module and now I want to convert it into an isolator.After some search on the internet I have found that a circulator can be converted into an isolator by making one of the ports of a circulator loaded with a 50 ohm load.
I am stuck at the point that how to make this port loaded?I tried placing a slab of some materials like 'barium titanate' which have good microwave absorbing properties but it didn't work.
anyone here who could give me some hints?
Regards,

You can assign any impedance to a port.
