An apparatus and method for providing adaptive control of the output of a radio frequency coupler. A plurality of input signals is provided to a multi-prong divider/combiner, the divider/combiner having a first and a second input terminals communicating a first and a second input signals with a first and a second prong of the divider/combiner, the divider/combiner dividing/combining said signals into at least one output signal. A first auxiliary signal is provided to a receiving terminal of a first transmission line, the first transmission line electromagnetically manipulating signal transmission in the first prong such that a first manipulated signal is substantially different in magnitude than the first input signal and dividing/combining the manipulated signal and the second input signal to provide a controlled output signal.
