Systems and methods for a modular ferrite switch for constructing switch networks are provided. In one implementation, a circulator redundancy network comprises multiple inputs; multiple outputs; and multiple circulator modules that connect the inputs to the outputs. A circulator module includes at least one module input connected to at least one input; at least one module output, where the number of module outputs equals the number of module inputs; multiple interconnection ports, configured to connect the circulator module to other circulator modules; and multiple circulators that route received signals between the at least one input, the at least one output, and the interconnection ports. Further, multiple interconnects connect the plurality of circulator modules to one another at the interconnection ports; and a circulator switch controller controls the direction of circulation for the plurality of circulators.

Modular ferrite switch for constructing switch networks

The present invention is directed to a circuit assembly that includes an integrated circulator assembly. The circuit assembly has a first substrate, which contains a continuous circuit trace that includes a circulator component from the circulator assembly and at least one electrical component from the circuit assembly. A second substrate is disposed beneath the first substrate and includes a cladding on one surface. The second substrate contains an aperture that accepts a ferrite element, which is axially aligned with the circulator component of the circuit trace. A conductive material is placed across the ferrite element so that it forms a continuous ground plane with the cladding, which is common to the entire circuit trace. The circulator assembly also contains a magnet bonded to the ferrite element. The circulator assembly may also include a yoke disposed below the magnet to shield the circulator from external magnetic fields.
