Abstract
A four-way non-directional power combiner employing cascaded 2:1 impedance step-up and step-down hybrid two-way combiners such that the use of additional impedance matching transformers is not required is disclosed. Unlike prior art combiners, the combiner disclosed employs a simple design which requires as few as eight transmission lines and four even mode impedance inhibitors, which may comprise ferrite cores. The non-directional signal combiner utilizes the inherent impedance transformation characteristics of a hybrid circuit in a four-way combiner, thereby eliminating the need for impedance matching transformers, and wherein the step-up and step-down hybrid circuits are interconnected in a balanced arrangement, thereby eliminating transmission line sections resulting in a shorter signal path with reduced losses from input to output.
