ABSTRACT:
A structure according to the present invention relates to the non-reciprocal microwave device such as circulator/isolator and includes the circuit, a ferrite member and a dielectric film. The circuit has three arms, each composed of two branches incorporating multiple strips. The branches are folded over a ferrite and isolated from each other by dielectric films to compose a multi-layer structure coupled with ferrite. The branches and strips are shaped to minimize the overall thickness of layer structure and to avoid triple crossover at intersections. The described assembly method allows maintaining symmetry between the ports of circulator/isolator. The broadband and high power operation of resonant structure is achieved by minimizing the asymmetry and improving the power distribution over the entire ferrite area.
