Hi,
I just want to know the behaviour of a Quadrature Hybrid Coupler if the signals of equal power but with different phases are applied at the output of the coupler as shown below.

If they are 90 deg phase difference, you can get 3dB more power from in or iso port, and about -20dB (ideally, no power) from the other port .
