Description
The University of Birmingham have been working with collaborators on 3D printed passive circuits for some time. This cluster of work will be reviewed, picking our important aspects for space and other industries. Filters based on coaxial cavities, spherical resonators and rectangular waveguide cavitiesat 3GHz, 10GHz and 100GHz respectively, have been designed, manufactured and tested. The metal coated polymer components show excellent microwave performance. Measurements of the temperature dependence of the ceramic based spherical resonator filter will be discussed. In addition, an OMT and filtering Butler matrix used for a multiport amplifier will be discussed. The Butler matrix was at 12 GHz and printed from metal. The advantages and disadvantages of the additive manufacturing technique will be highlighted throughout.
JUSTIFICATION FOR THE CONSIDERATION
This presentation covers a lot of research and over a wide frequency range with novel components. The novelty expresses the advantages of the 3D printing.
