Key Engineering Features

Superior Electrical Performance

You want your RF systems to have the minimum possible signal deterioration across broad ranges of frequencies. The connection has good VSWR performance and minimal insertion loss across its operating frequency range of DC-12.4GHz.

The center and outside contacts are gold plated to provide superior conductivity with a center contact resistance of less than 3.0mΩ. This precise engineering reduces signal reflection and is perfect for high frequency applications where every decibel counts.

Robust Mechanical Construction

Its threaded coupling system offers robust and vibration-resistant couplings that are vital to mobile and aeronautical applications. Enjoy reliable performance via repeated installs with guaranteed 500 mating cycles.

The straight male interface is completely intermateable with normal SMA and 2.92mm connections. That commonality makes it easier to integrate into your systems and will simplify inventory complexity for your procurement staff.

Environmental Resilience

Wide operating temperatures (-65℃ to +125℃) for demanding applications. The dielectric of the PTFE is stable in this temperature range and the silicon rubber sealing is providing protection against moisture.

High dielectric withstanding voltage (1,000V) and insulation resistance (more than 5,000MΩ) allow safe operation in high-voltage situations. Its features make it well-suited for power-critical applications where electrical safety is of primary concern.

Industrial Applications

Aerospace and Defense Systems

This connection is used in avionics, radar systems and communication equipment where great temperature stability and mechanical endurance are required. Its broad working temperature range makes it suitable for use in air vehicles and satellites.

Telecommunications Infrastructure

Its low-loss properties make the connection a good match for 5G base stations and signal distribution networks. Dependable high frequency performance for future generation wireless systems now available for your telecom installations.

Test and Measurement Equipment

Laboratory instrumentation and network analyzers require repeatable, precision connections. The SMA Male Straight Connector for RG142 Cable's consistent electrical performance supports accurate measurements in research and quality control environments.

Industrial Electronics

Manufacturing automation and process control systems utilize these connectors for RF signal distribution. The robust construction withstands industrial vibration and temperature fluctuations.

Quality Assurance Process

Electrical Testing Standards

SIPU implements insulation and dielectric withstanding voltage testing using specialized equipment for every production batch. The structural design inherently ensures VSWR and insertion loss performance through precision manufacturing.

Each connector undergoes insulation resistance verification at 1,000V to confirm electrical integrity. These tests validate the connector meets specified electrical parameters before shipment.

Plating and Material Verification

Every production batch receives plating thickness inspection and adhesion testing. X-ray fluorescence analysis confirms gold plating meets thickness specifications for optimal conductivity and corrosion resistance.

RoHS environmental compliance testing on each batch ensures your products meet international environmental regulations. This documentation supports your own compliance reporting requirements.

Manufacturing Controls

ISO 9001 certified processes govern production from raw material inspection through final testing. Precision CNC machining maintains tight tolerances essential for consistent RF performance.

Dedicated inspection protocols verify thread dimensions and contact alignment. This attention to detail ensures reliable mating with standard SMA interfaces across manufacturers.

Installation Considerations

Proper Termination Technique

Soldering the center conductor provides maximum signal stability and lowest contact resistance. Clean, flux-free joints prevent future corrosion and maintain electrical performance over the connector's service life.

The outer conductor requires secure attachment to the cable shield. Proper assembly ensures 360-degree shield continuity critical for maintaining specified shielding effectiveness.

Cable Compatibility

This connector is specifically engineered for RG142 cable geometry. The dimensional fit ensures proper dielectric spacing and impedance matching throughout the transition from cable to connector.

Using connectors designed for your specific cable type prevents impedance discontinuities that degrade high-frequency performance. Match connector specifications to cable parameters for optimal results.

Packaging and Logistics

Each connector ships in protective packaging designed to prevent mechanical damage and contamination during transit. Bulk orders receive organized packaging that simplifies inventory management and installation workflows.

Standard packaging includes electrostatic discharge protection for sensitive RF components. Documentation accompanies each shipment with specifications and test certificates for your quality records.
