Hello,In a 3dB coupler we have a property where between the output we have 90 degree phase.
We can construct the 3dB coupler by taking two 8.34dB couplers as shown in the article bellow.
But in the article page 2,we have a calculation where they take 45 degrees and get 3dB from that?
What is this 45 degrees? is it somehow linked to our 90 degree property ?
Thanks.
