  • Multi-junction waveguide circulator without internal transitions
    Patent number: 6885257
    Abstract: An improved multi-junction waveguide circulator that eliminates the transitions to dielectric transformers and air-filled waveguides between ferrite elements is described. The waveguide circulator in accordance with the invention can be implemented in variations from a minimum of two ferrite circulator elements held in close proximity to one another to any number of ferrite elements as required to achieve the desired isolation performance or to create a switch matrix with any combination of input and output ports. The waveguide circulator in accordance with the invention eliminates the transitions between adjacent ferrite elements and thus reduces losses, component size, and mass.
