A rectangular waveguide device is provided. The rectangular waveguide device comprising: a first broad wall; a second broad wall parallel to the first broad wall; a first narrow wall perpendicular to and connected to the first broad wall and the second broad wall; a second narrow wall parallel to the first narrow wall and connected to the first broad wall and the second broad wall; and at least one slot in the first broad wall.

Apparatuses and methods for mode suppression in rectangular waveguide

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.
