Abstract:
A method for combining first and second fixed-phase-related input signals without incurring combining loss, said first and second fixed-phase-related signals being of a common or harmonically-related frequency and of arbitrary magnitude relationship comprising:combining said first and second input signals in-phase in a first four-port combiner having at least first and second input ports and at least first and second output ports; reflecting back to both said first and second input ports from both said first output port and said second output port said fixed-phase-related signals while introducing a quadrature phase differential in all signals reflected from only one of said first and second output ports to produce first and second reflected signals; thereupon redirecting said first and second reflected signals to a second combiner; and combining signals from said redirecting step to produce a combined signal such that the magnitude of the combined signal is a constant sum corresponding to the maximum magnitude of one of the following: said first input signal; the sum of said first input signal and said second input signal.
