ABSTRACT:
An impedance transforming hybrid ring has a non-uniform impedance ring structure coupled to four ports. Two of the ports function as input ports, the remaining two as output ports. An arbitrary relationship exists between the impedance of the input ports and the impedance of the output ports. The power division between output ports may be selected as a matter of design choice. A broad band phase reversing network is utilized to provide an impedance transforming hybrid ring which efficiently operates over octave bandwidths. Design equations are provided and method for utilizing same are disclosed.
