Phase Matching

This is defined as coax cable assemblies that require the same electrical length, specified in degrees at a determined frequency. The tolerance of this match is heavily dependent on absolute coax length, operational temperatures, connector quality and assembly techniques.

Our Capabilities Include:

• Assemblies can be matched to an established standard or to other cables in a set.
• Phase matched cables can be provided with tolerances of a +/-3 degrees, application and materials dependent.
• Thermal stress relief cycling is required to achieve consistent matching.
• Agilent ENA Network Analyzer is used for the measurement of electrical length.

What are coaxial cable assemblies used for?

Coaxial cable assemblies are commonly used in RF and high-frequency applications that require reliable signal transmission. They are found in telecommunications, aerospace, defense, test and measurement equipment, wireless communications, radar systems, and other electronic systems. The design of a coaxial cable helps maintain signal integrity while minimizing interference and signal loss.

What connector configurations are available for coaxial cable assemblies?

Coaxial cable assemblies can be manufactured with identical connector types, dissimilar connector types, or different connector genders depending on application requirements. Terminations may utilize direct solder attachments or crimp and solder combinations. This flexibility allows cable assemblies to be customized to meet specific electrical, mechanical, and installation requirements.

What is phase matching in a coaxial cable assembly?

Phase matching ensures that multiple cable assemblies within a set have the same electrical length when measured at a specified frequency. This is important in applications where signal timing and synchronization must be tightly controlled. Factors such as cable length, operating temperature, connector quality, and assembly techniques can all affect phase-matching performance. Cable sets can be matched to a reference standard or to one another, with tolerances as tight as ±3 degrees depending on materials and application requirements.

What coaxial cable sizes can be supported?

Epec supports a variety of coaxial cable sizes to accommodate different electrical and mechanical requirements. Available size capabilities include 0.020", 0.031", 0.047", 0.070", 0.086", 0.120", and 0.141" coaxial cables. The appropriate cable size is selected based on factors such as frequency, signal loss requirements, power handling needs, flexibility, and installation constraints.

What industry standards are used for coaxial cable assembly manufacturing?

Coaxial cable assemblies can be manufactured to IPC and military specifications depending on application requirements. Standards referenced include IPC-A-610 Class 3 for electronic assemblies, MIL-C-17 for coaxial cables, MIL-DTL-87104 for airborne electronic system cable assemblies, MIL-C-39012 for RF cable connector performance, and MIL-STD-202 for thermal shock testing. Adherence to these standards helps ensure consistent quality, performance, and reliability in demanding environments.
