More compact ferrite circulator junctions with predicted performance

The analysis of two novel types of three-port junction circulator is discussed in detail, and, neglecting losses, graphs of the predicted performance of specific theoretical designs are shown. The first type of circulator is based on a ferrite ring, and it is shown that by appropriately selecting the ratio of the inner/outer radius of the ring the need for transformers can be eliminated. The second type is based on a three-port ferrite disk with two ports positioned 60 away from a middle port. This provides a more compact layout and a design for 94 GHz is presented.<
