A multi-junction circulator assembly comprises a waveguide housing including first and second sets of waveguide arms, and a junction section therebetween. A first circulator component located in the waveguide housing comprises a ferrite element including a plurality of leg segments, with one of the leg segments extending toward the junction section. A second circulator component located in the waveguide housing operatively communicates with the first circulator component and comprises a ferrite element including a plurality of leg segments, with one of the leg segments extending toward the junction section. A dielectric transition segment is located in the junction section between the leg segments of the ferrite elements that extend toward the junction section. The dielectric transition segment is separated from the leg segments by opposing gaps at opposite ends of the dielectric transition segment. The gaps provide dielectric-free regions in the direction of signal flow between the ferrite elements.
