Nested Coaxial Power Divider for High-Power Microwave Applications

The patent employs nested coaxial conductors where inner conductors are placed within outer conductors, creating a compact multi-conductor structure. This nesting arrangement achieves complex power division/combination functions with fewer discrete components, reducing overall device complexity while maintaining the electrical ruggedness needed for high-power applications.

Multiple conductor functions are merged into a single integrated structure. The nested coaxial configuration combines multiple transmission paths and impedance transformations within one unified device, eliminating the need for separate components and reducing fabrication complexity while preserving high-power capability.

The nested coaxial conductor structure achieves compact device length by placing conductors within conductors. The standardized nested geometry provides clear dimensional relationships that guide manufacturing, reducing the impact of precision requirements compared to more complex non-nested configurations.

The patent uses standardized unit element conductor dimensions and spacing parameters that optimize bandwidth performance. By establishing fixed geometric relationships between nested conductors, the design achieves broad bandwidth while providing clear manufacturing specifications that manage precision requirements.

The nested coaxial structure creates naturally enclosed spaces between conductors that can be sealed with O-rings. This nesting geometry provides built-in pathways for gas filling and sealing without requiring additional external components, reducing the complexity increase associated with gas sealing.

O-rings are introduced as intermediary sealing elements between the nested conductors. These simple elastomeric components provide effective gas sealing to prevent dielectric breakdown, adding minimal complexity while significantly improving the breakdown strength of the air dielectric.
