Hello, there is an implementation of a coupler shown below,the problem is that i need ports 2 and 3 to be 90 degrees between each other.
but in the implementation bellow i have 180 degrees between ports 2 and 3 ,port 4 is isolation.
Is there a way to change the implementation below so between ports 2 and 3 i will have 90 degrees and port 4 is isolation?
Thanks.
