1. Secure 2-Hole Flange Panel Mounting
The SMA female right-angle connector is integrated with a 2-hole square flange. This design allows for secure, flush mounting directly onto chassis panels or PCBs, providing a highly stable anchor point that withstands mechanical stress and vibration during installation and operation.
2. High-Frequency 086 Cable Performance
The 086 RF cable is specifically engineered for high-frequency signal transmission. Its solid silver-plated copper center conductor and extruded PTFE dielectric ensure minimal signal attenuation and precise 50-ohm impedance matching, making it ideal for microwave and millimeter-wave applications.
3. Space-Saving Dual-Profile Design
Combining a right-angle SMA panel connector with a miniature MCX plug allows for optimal cable routing in confined spaces. The 90-degree SMA connector prevents sharp cable bends at the panel, while the MCX connector saves critical board space inside the enclosure.
4. Superior EMI/RFI Shielding
The 086 cable features a high-coverage (>95%) silver-plated copper braid. This provides outstanding shielding effectiveness, preventing signal leakage and protecting sensitive RF signals from external electromagnetic interference in dense electronic environments.
5. Factory-Direct Precision Assembly
As a direct manufacturer, we utilize automated precision crimping and soldering processes for the 086 cable. This ensures consistent electrical performance, reliable mechanical retention, and strict adherence to aerospace-grade quality standards.

1. Precision CNC Machining
All SMA and MCX connector bodies are machined from high-purity brass using precision CNC equipment to ensure exact dimensional tolerances, guaranteeing flawless mating and consistent electrical performance.
2. 100% VNA Electrical Testing
Every single 086 cable assembly undergoes rigorous testing using a Vector Network Analyzer. We verify VSWR, insertion loss, and return loss across the specified frequency range to ensure compliance with high-frequency RF specifications.
3. Hi-Pot Dielectric Withstanding Voltage Test
Each assembly is Hi-Pot tested to validate the integrity of the PTFE dielectric insulation, preventing arcing and signal leakage, and ensuring safety and reliability under high-voltage bias conditions.
4. Torque and Pull-Force Testing
SMA flange connectors are torque-tested to verify thread strength and secure panel attachment. Both ends are subjected to pull-force testing to guarantee the cable-to-connector terminations can withstand installation tension.
Packaging & Logistics
• Standard Packaging: Cables are carefully coiled to their minimum bend radius and sealed in anti-static, moisture-proof bags to prevent oxidation and physical damage during transit.
• Labeling: Each bag is clearly labeled with the part number, cable type (086), length, and revision number for full traceability.
• Lead Time: In-stock standard configurations ship within 24 hours. Custom lengths and configurations typically require 5-7 business days.
• MOQ: 1 piece for standard configurations; 50 pieces for custom cable length or connector plating runs.
Q1: What is the advantage of using 086 cable over standard RG316?
A: The 086 cable is specifically designed for high-frequency applications. It features a solid center conductor and specialized PTFE dielectric that provides significantly lower insertion loss and better VSWR at frequencies above 6 GHz, making it ideal for microwave and mmWave signals.
Q2: Why choose a 2-hole flange for the SMA connector?
A: The 2-hole flange provides a highly secure, vibration-resistant panel mount. Unlike standard threaded panel connectors, the flange design prevents the connector from rotating during mating and distributes mechanical stress evenly across the chassis.
Q3: What is the minimum bend radius for the 086 cable?
A: To maintain signal integrity and prevent damage to the internal dielectric, the minimum bend radius for the 086 cable is typically 8.9 mm. Avoid bending the cable tighter than this specification during installation.
Q4: Can this assembly be used for DC power applications?
A: Yes, the 086 cable can carry DC power. However, due to its small diameter (2.18mm) and solid center conductor, please consult the current-carrying capacity derating table to ensure it meets your specific power delivery requirements without overheating.
1. Use Proper Torque: When mating the SMA connector, use a torque wrench set to 35 in-lbs (4.0 N·m). Over-tightening can strip the threads or deform the center pin.
2. Maintain Bend Radius: Avoid bending the 086 cable tighter than its minimum bend radius (8.9 mm) to prevent kinking the center conductor or crushing the PTFE dielectric.
3. Handle by the Connector Body: When connecting or disconnecting, always grip the connector's hex body, not the cable. Pulling on the cable can damage the strain relief and internal termination.
4. Keep Connectors Clean: Ensure the mating surfaces of both connectors are free of dust and debris before connection to maintain optimal shielding and impedance matching.
