Micro coaxial cables are essential for transmitting high-frequency signals in compact devices like smartphones, medical equipment, wearables, and advanced sensors. A critical factor influencing their performance is the plating on the conductor – commonly silver or gold. Understanding their differences is crucial for optimal design.
Silver-Plated: Superior Conductivity. Silver is the most electrically conductive metal at room temperature. Silver plating minimizes signal attenuation (loss) across a wide frequency spectrum, particularly beneficial in applications exceeding 1 GHz (common in micro coax). This translates to stronger signals over longer runs or with complex cabling needs.
Gold-Plated: Good Conductivity, but Less than Silver. Gold’s conductivity is about 76% that of copper (whereas silver is ~106%). Gold-plated micro coax inherently has higher resistive loss compared to silver-plated versions at equivalent geometries and frequencies. Its advantage lies elsewhere (durability).
Silver-Plated: Susceptible to Oxidation. Silver forms a sulfide tarnish layer when exposed to atmospheric sulfur compounds or moisture. This tarnish increases surface resistance and degrades signal integrity over time, especially affecting very high frequencies due to the skin effect (where signal travels near the conductor surface). Performance degrades faster in harsh environments (high humidity, pollution, salt spray).
Gold-Plated: Excellent Corrosion Resistance. Gold is highly inert and does not oxidize or tarnish under normal conditions. This makes gold-plated micro coax exceptionally reliable for maintaining stable contact resistance and consistent signal performance over extended periods, even in challenging environments. Reliability is its primary strength.
3. Signal Integrity at Extreme Frequencies
Silver-Plated: Excellent for Ultra-High Frequencies… Initially. Before significant tarnish forms, silver’s high conductivity provides exceptional high-frequency performance. However, as tarnish develops, the surface resistivity increases, causing progressive high-frequency signal loss.
Gold-Plated: Consistent High-Frequency Performance. Gold maintains a stable, low-resistance surface regardless of exposure to air or mild contaminants. While its base conductivity is lower, its consistent surface properties ensure predictable signal integrity at high frequencies over the cable’s operational lifespan without degradation from oxidation.
4. Contact Resistance Stability
Silver-Plated: Variable. Contact resistance can increase significantly over time due to silver tarnishing. This is critical for connections relying on spring contacts or separable interfaces.
Gold-Plated: Highly Stable. Gold’s inert nature provides extremely stable and low contact resistance over time. This is vital for connectors with wiping contacts or in applications demanding constant, reliable electrical connections without intermittent failures.
5. Mechanical Durability (Limited by Base Metal)
Both silver and gold platings are relatively thin layers (microns) applied over a base conductor (usually copper or copper alloy). The mechanical durability (wear, kink resistance, flexibility) of the micro coax cable itself is predominantly determined by the base conductor, dielectric materials, and braid/shield construction, not primarily by the plating type.
6. Cost
Silver-Plated: Lower Cost. Silver is significantly less expensive than gold, making silver-plated micro coax the more cost-effective solution where very long life or extreme environments aren’t paramount.
Gold-Plated: Higher Cost. Gold is a very expensive precious metal. The material cost and more complex plating processes make gold-plated micro coax considerably more expensive than silver-plated alternatives.

Conclusion: Choosing the Right Plating
Choose Silver-Plated Micro Coax When:
Minimizing initial signal attenuation is the absolute top priority.
Operating frequencies are very high (GHz range).
The environment is controlled (low humidity, low sulfur/pollution).
The application has a shorter expected lifespan or cost is a major constraint.
Connections are soldered or otherwise permanent/sealed, minimizing contact oxidation risk.
Choose Gold-Plated Micro Coax When:
Long-term reliability and stable signal integrity are paramount (critical systems).
The device operates in harsh environments (high humidity, industrial settings, salt air).
Connections involve separable interfaces or spring contacts prone to intermittent failures.
Maintaining stable low contact resistance is critical.
The cost differential is acceptable for the required performance guarantee.
The choice hinges on the application’s specific demands for performance stability over time versus initial signal loss and cost. Gold provides longevity and resilience where it matters most, while silver offers peak electrical performance under controlled conditions at a lower cost.
