*Notes:

“A” is the amplitude of the applied signals. When two quadrature signals with equal

amplitudes are applied to the coupler as described in the table, they will combine at the output

port. If the amplitudes are not equal, some of the applied energy will be directed to the isolated

port.

The actual phase,
