RF Coaxial Connector Bodies

RF Coaxial Connector Bodies are foundational components in RF interconnects, directly affecting signal integrity, thermal stability, EMI performance, and mechanical endurance. These machined housings serve as the structural and electrical backbone of the connector assembly, where even minor deviations in form or finish can lead to substantial system-level failures. The following points address how precision-engineered RF Coaxial Connector Bodies resolve key pain points encountered in demanding RF applications. 

Material Specification

Brass C36000 (ASTM B16), Stainless Steel 303 (ASTM A582), Beryllium Copper (ASTM B194, C17200)

Dimensional Tolerances

±0.005mm (Inner/Outer Diameter), ±0.01mm (Length), Thread Pitch – ±0.002mm

Surface Finish

Ra ≤0.4µm (Contact Surfaces), Ra ≤0.8µm (Non-Critical), Rz ≤3.2µm (Thread Flanks)

Concentricity/Coaxiality

≤0.005mm TIR (Center Conductor Bore), ≤0.01mm (Outer Body)

Perpendicularity

≤0.01mm (Face to Axis), ≤0.005° (Thread to Axis)

Product Description

RF Coaxial Connector Body geometry dictates the impedance uniformity along the signal path. Any radial misalignment or dielectric cavity offset within the body causes localized impedance variation, generating return loss and ripple across the passband. A high-precision RF Coaxial Connector Body maintains concentricity between the center conductor bore and outer shield within ±10 µm, ensuring a continuous 50-ohm or 75-ohm transmission environment. This preserves S11 parameters and suppresses signal reflections in high-frequency transceiver chains.

Thread Specifications

SMA (1/4″-36 UNEF), N-Type (5/8″-24 UNEF), Class 3A/3B Fit, Thread Pitch – ±0.001mm

Plating

Gold Plated (1-3µm, MIL-G-45204), Nickel Underplate (2-5µm), Passivated (SS, ASTM A967)

Cleanliness Requirements

Particle Count ≤5mg/m² (ISO 16232), No Residual Oils (IPA Wipedown), Ionic Contamination <1.0µg/cm²

Certification Standards

MIL-PRF-39012, IEC 61169, RoHS/REACH Compliant, ISO 9001

Technical Advantages

RF Coaxial Connector Bodies that lack uniform conductive enclosures or have insufficient ground contact mechanisms are vulnerable to electromagnetic leakage. This interferes with nearby analog circuits and compromises system-level EMC compliance. A shield-optimized RF Coaxial Connector Body includes 360° machined contact fingers, conductive gaskets, and unified barrel enclosures with no parting gaps. These features collectively deliver shielding effectiveness beyond 110 dB across 1–18 GHz, protecting the signal chain from both ingress and egress EMI. 

RF Coaxial Connector Bodies in high-power systems face thermal loading due to conductor losses and reflected power. Without sufficient thermal conductivity and uniform contact pressure, the connector body becomes a hotspot, accelerating dielectric aging and metal fatigue. A thermally robust RF Coaxial Connector Body employs CuZn or BeCu substrates with >300 W/m·K conductivity and surface plating stacks (Ni–Au or Ni–Ag) that reduce thermal resistance at the interface. These configurations maintain thermal equilibrium during >100 W continuous RF transmission.

RF Coaxial Connector Bodies

Mechanical Instability Under Vibrational and Shock Loads

In aerospace and military RF systems, mechanical stresses from vibration and repeated shock can compromise connection stability. A standard RF Coaxial Connector Bodies may experience fretting at the threads or lose axial retention under such conditions. A ruggedized RF Coaxial Connector Bodies counters this with deep-thread profiles, anti-rotation keys, and compliance to MIL-STD-202 Method 204 and Method 213 standards.  

Production lines utilizing automated or semi-automated connector installation suffer yield loss when connector bodies vary in dimensions like mating length, flange thickness, or thread major diameter. A dimensionally stable RF Coaxial Connector Body is CMM-verified and held to ±0.01 mm tolerances in all critical dimensions, including dielectric seat depth and engagement length.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure consistent clamp pressure across different tubing hardness levels?

Frigate calibrates each clamp using programmable force profiles specific to the durometer rating of the tubing. Custom spring constants and cam geometries are applied to maintain occlusion force within ±2%. This ensures flow cut-off without collapsing or damaging tubing walls. Finite element simulation is used to model contact stress zones before prototyping. 

What methods does Frigate use to validate the dimensional accuracy of clamp jaws for high-cycle reliability?

Clamp jaws are CNC machined and validated using optical CMM with ±10 μm resolution. Frigate applies GD&T principles to control flatness, parallelism, and perpendicularity of the jaw faces. These tolerances are critical to maintaining uniform contact pressure over >50,000 actuation cycles. Surface roughness (Ra) is also controlled below 0.8 μm to prevent tubing abrasion. 

How does Frigate address wear and friction in high-frequency clamp actuation systems?

Frictional wear is minimized using tribologically optimized materials like PTFE composites or DLC-coated stainless steel. Frigate tests wear coefficients under simulated actuation profiles exceeding 100,000 cycles. Real-time data from endurance rigs help determine the lowest possible coefficient of friction while maintaining grip. Clamp surfaces are treated for hardness and low-friction interaction with silicone and PVC tubing. 

 

What mechanical feedback features does Frigate integrate for clamp position verification in automated dialysis machines?

Frigate incorporates magnetic or optical position sensors directly into the clamp mechanism. These sensors verify open/closed states within 20 ms for integration into closed-loop control systems. Signal debouncing and positional hysteresis thresholds are calibrated to ±1°. This ensures the machine responds immediately to occlusion errors or unexpected clamp disengagement. 

How does Frigate prevent clamp failure due to thermal or humidity exposure in clinical environments?

Material selection considers coefficient of thermal expansion and hygroscopic behavior under IEC 60601 operating conditions. Frigate uses stabilized polymers and anodized aluminum to prevent clamp warping or creep. Accelerated life testing at 40°C/90% RH for 96 hours validates geometry retention. Clamp mechanisms are also designed with slotted geometries to allow uniform thermal expansion.
