SMA Female Flange Mount 18GHz Specifications

Key Product Features

Broadband High-Frequency Performance

The connection covers the whole DC to 18 GHz frequency range and is excellent for medium to high frequency signal transmission. This means your RF systems will have constant impedance matching and low signal reflection throughout the whole frequency range.

Rugged Flange Mounting

The 4-hole flange construction enables for secure mechanical anchoring to panels and enclosures. This increasing design inhibits rotation and provides consistent alignment, which is crucial for preserving electrical performance under vibration and heat cycling.

Premium Material Construction

Beryllium bronze center contacts with gold plating deliver low contact resistance and excellent corrosion resistance. The stainless steel outer conductor with passivation treatment withstands harsh environmental conditions. PTFE dielectric maintains stable electrical properties across wide temperature ranges.

Low Insertion Loss & Excellent VSWR

With insertion loss formula-controlled performance and VSWR remaining below 1.05 + 0.012F(GHz), your signal integrity stays intact. These specifications ensure efficient power transfer and minimal distortion in critical RF paths.

Stringent Quality Control Process

SIPU implements multi-layer inspection protocols to guarantee product reliability. Each batch undergoes plating thickness verification and binding force testing to ensure coating integrity. RoHS environmental compliance testing is performed per batch to meet global regulatory standards.

Dielectric withstanding voltage testing validates insulation performance using specialized high-voltage test equipment. Insulation resistance measurements confirm electrical isolation exceeds 5,000 MΩ. The connector's structural design inherently ensures VSWR and insertion loss performance through precision engineering and controlled manufacturing tolerances.

Every production run includes dimensional verification of critical features. The inner conductor tail dimensions (0.5 mm slot width × 1.5 mm slot depth) are inspected to ensure proper PCB mounting. Mating cycle testing validates mechanical durability exceeds 500 connections.

Primary Application Sectors

Telecommunications Infrastructure

The SMA Female Flange Mount 18GHz serves as a reliable interface in 5G base stations and microwave backhaul systems. Your equipment benefits from stable connections between internal circuitry and external antenna ports.

Aerospace & Defense Systems

Phased-array radar systems and electronic warfare equipment rely on this connector's mechanical stability. The flange mount withstands extreme vibration and G-forces encountered in airborne and mobile platforms.

Test & Measurement Equipment

Vector network analyzers and signal generators incorporate this connector for accurate RF characterization. The 18 GHz rating ensures your test equipment performs precise measurements without introducing parasitic effects.

Industrial RF Systems

Manufacturing test fixtures and automated RF testing systems utilize this connector for repeatable performance. Your production lines maintain consistent electrical characteristics across high-volume operations.

Installation & Maintenance Guidelines

Mounting Instructions

Secure the connector to your panel using all four flange mounting holes. Ensure flat contact between the flange and mounting surface for optimal grounding. Use appropriate torque values when tightening mounting hardware to prevent deformation.

Connection Best Practices

Align the mating connector carefully before engagement. Rotate the coupling nut smoothly without forcing. Proper alignment extends the connector's mating cycle life and maintains electrical performance.

Environmental Considerations

While the connector operates reliably from -65℃ to +125℃, avoid rapid temperature transitions when possible. Allow gradual thermal equalization in extreme environments. The passivated stainless steel and gold plating resist corrosion in most industrial atmospheres.
