What materials are used to manufacture waveguide-coaxial adapters
1. Primary Housing Alloys
- Aluminum alloys – lightweight, mechanically stable, easy to precision machine.
- Copper alloys – used when enhanced thermal conductivity or specific electromagnetic characteristics are required.
- Ensures precise geometric dimensions and structural integrity under varying environmental conditions.
2. Advanced Surface Finishes
- Gold plating – superior corrosion resistance, consistent low‑loss contact over repeated mating cycles.
- Silver plating – preferred for high‑power applications where maximum conductivity is critical.
- Protective finishes maintain long‑term reliability and optimal RF performance.
3. Internal Dielectric Supports
- PTFE (Teflon) – widely used for exceptional electrical insulation and minimal signal attenuation at high frequencies.
- Precisely positions and supports the center conductor without degrading the electromagnetic signal.
- Dielectric beads hold internal probe in place with low loss.
4. Precision Coupling Probes
- Beryllium copper or gold‑plated brass – highly conductive metals for efficient energy coupling.
- Withstands mechanical stress while maintaining signal integrity.
- Probe shaping and positioning determines bandwidth and impedance matching – material selection is critical.
