Overview

The standard SIST HD 351.5 S1:2004, published by the CLC, specifies the geometrical configuration and mounting provisions for a 50 ohm 3.5 mm rigid precision coaxial line. This standard is part 5 of a series covering rigid precision coaxial lines and their associated precision connectors, ensuring reliability and consistency for high-frequency RF applications. Originating from the International Electrotechnical Commission (IEC) publication IEC 60457-5:1984, this standard provides the foundational dimensions and tolerances for manufacturing and interfacing coaxial lines designed for precision performance.

Key Topics

• Rigid precision coaxial line configuration
  Defines the exact geometry including diameters, lengths, and threading dimensions for the 3.5 mm coaxial line ensuring minimal signal loss and high mechanical stability.

• 50 ohm impedance specification
  The coaxial line maintains a consistent 50 ohm impedance, critical for RF signal integrity and minimal reflection.

• Provision for connector mounting
  Precise details on how connectors are mounted to the coaxial lines, including thread sizes and mounting surfaces, ensuring compatible and secure connections.

• Dimensional tolerances
  Provides strict measurement tolerances (e.g., ±0.0005 in) to maintain uniformity and interchangeability across components and manufacturers.

• International consensus
  Developed by IEC Technical Committee 46D, this standard reflects a global agreement on reliable coaxial line design used in telecommunications and RF equipment.

Applications

• RF and microwave communication systems
  Used extensively where low-loss and high-precision signal transmission at microwave frequencies are required.

• Test and measurement equipment
  Ideal for precision test fixtures and calibration standards requiring consistent coaxial line characteristics.

• Telecommunications infrastructure
  Ensures interoperability and performance in rigid RF cables linking antennas, transmitters, and receivers.

• Laboratory and research environments
  Provides a standardized coaxial pathway for experimentation, design validation, and component testing.

Related Standards

• IEC 60457 series
  Other parts in the IEC 60457 series cover different coaxial line types and connector configurations, allowing comprehensive guidance for various coaxial applications.

• HD 351 series
  The broader CLC HD 351 suite provides standards covering coaxial cables and connectors, ensuring full ecosystem compliance.

• 50 ohm coaxial cable standards
  Other industry standards complementing this document, focusing on cable flexibility, shielding, and environmental resistance.

Practical Value

For engineers and designers working with high-frequency coaxial transmission lines, adherence to SIST HD 351.5 S1:2004 ensures:

• Compatibility across international markets due to standardized dimensions and mounting.

• Reduced signal reflection and loss through strict impedance and geometrical control.

• Reliable assembly and maintenance with clearly defined connector mounting provisions.

This standard serves as a critical reference for manufacturers, testing labs, and communication service providers aiming to achieve precision and quality in coaxial line applications.
