ABSTRACT:
An RF coupler incorporating a pair of branch circuits which combine first and second input signals supplied at the same impedance level, amplitude and phase into an output signal at the same impedance level, twice the amplitude and phase shifted with respect to the input signals when both input signals are present, and which, if only one of the input signals is present, passes that input signal through its branch circuit to the output without loss, while terminating the branch circuit associated with the absent input signal with an equal impedance.
