Abstract
Two or more reflective isolator elements are joined at their outputs to produce an RF combining structure. An RF circulator element is used for each input RF signal as a reflective isolator element to provide a different phase delay according to the direction of propagation of the RF wave. The output of the reflective isolator elements thus exhibits a high output impedance, when looking into the RF output port, preventing back propagation of signals from one input port to another.
