This paper presents a conventional analysis for narrowband operation using odd-even technique for the ideal structures of the Branch-line and Rat-Race Hybrids. Additionally, it presents the simulated results obtained whit Ansoft Designer <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> platform, using ideal transmission lines in order to characterize the hybrids through their merit parameters.
