directional coupler [hlp]

hi friends;
Can we use a directional coupler as a 90 degree phase splitter?

Quadrature couplers such as Lange Coupler produce 90° phase differences. These are 3dB couplers. When the value is less than 3dB for the name becomes (directional coupler), but it the same circuit and phase differences.


There's many ways to build directional couplers that have different phase differences.

That didn't help did it?!
