Three different versions of hybrid ring couplers are proposed in this paper. The first one is an improved version of an old distributed coupler. The other two couplers are broadband lumped-distributed hybrid ring couplers. Theoretical analyses, simulations, and practical measurements are covered in this paper. Moreover, the theoretical results are almost matching with the practical results, so these couplers are almost fully corresponded with the theoretical results. All designs and simulations are implemented by the Advance Design System (ADS) software.
