Technical Advantages

In thermally constrained systems, the High-Frequency Connector Shell integrates conductive metal alloys and passive heat spreading geometries. This aids in thermal dissipation while maintaining RF isolation, preventing contact degradation and dielectric drift during high-duty-cycle or continuous operation at elevated temperatures. 

The High-Frequency Connector Shell allows for compact multi-port integration without compromising signal integrity. Its internal shielding and dielectric barriers are optimized to isolate differential lines and prevent near-field coupling, preserving channel separation and timing alignment in systems above 10 GHz.

Corrosion and Environmental Fatigue Resistance

Built for environmental resilience, the High-Frequency Connector Shell utilizes chemically stable plating systems and corrosion-resistant base metals. This construction resists fretting, galvanic mismatch, and oxidation in harsh environments—ensuring long-term conductivity and signal integrity across mission-critical deployments. 

To ensure fitment across varied hardware platforms, the High-Frequency Connector Shell offers customizable mounting options including floating flanges, bulkhead interfaces, and blind-mate alignment features. These support mechanical compliance in tight stack-ups and eliminate strain-induced connector misalignment during system assembly.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure dimensional consistency in High-Frequency Connector Shells across production batches?

Frigate uses precision CNC machining with micron-level toolpath control to maintain concentricity and tolerance stack-up. All connector shells undergo in-process metrology using coordinate measuring machines (CMM). This ensures each shell meets exact axial symmetry and surface finish required for high-frequency impedance matching. Batch variation is minimized through strict process capability (Cp, Cpk) monitoring. 

How do Frigate’s connector shells mitigate galvanic corrosion in mixed-metal environments?

Frigate applies surface treatments like passivation, nickel-phosphorus plating, or tri-metal coatings based on the base metal and use environment. These layers prevent electrochemical mismatch between connector materials and mounting surfaces. This stops galvanic current flow that typically causes pitting and contact degradation. Shells are qualified under salt spray and humidity cycling standards.

Can Frigate support custom shell configurations for non-standard RF modules?

Yes, Frigate offers application-specific connector shell designs with custom flange mounts, standoff spacing, and internal shielding features. Engineers collaborate with customers to match mechanical constraints, RF layout, and environmental exposure. Finite element modeling (FEM) is used to validate thermal, structural, and EMI performance. Custom prototypes are CNC-machined and tested before scaling. 

 

How does Frigate verify RF shielding performance in its High-Frequency Connector Shells?

Frigate performs shielding effectiveness (SE) testing in controlled environments using TEM cells and spectrum analyzers. This quantifies attenuation across GHz ranges, identifying leakage paths or joint weaknesses. Shells are optimized for 360° grounding and minimum aperture loss. Each design is validated against MIL-STD or IEC shielding benchmarks depending on application. 

How do Frigate shells behave under thermal cycling and vibration stress?

Frigate uses simulation-driven designs to ensure connector shells withstand mechanical fatigue and expansion mismatch. Shells are tested in vibration tables and thermal chambers across -55°C to +125°C. Threaded, bayonet, or snap-in features are validated for retention force under dynamic load. This guarantees mechanical and electrical stability in harsh environments.
