Phase Matched Cable Assemblies

 

Using proprietary techniques, precision frequency and time domain measurements, our experienced staff will achieve consistent and reliable phase matched cable assembly performance. Whether it is pair, group or lot-matching, Rosenberger North America can process the most demanding phase matched cable assembly requirements with ease.  Phase matches may range from sub-picosecond  to 10s of picoseconds and even more,  with absolute, relative and delay-matching values.  Whether it is a high performance, air-spaced PTFE cable assembly, a precision-shaped semi-rigid cable assembly, or a polyethylene foam style cable assembly, Rosenberger North America is the best in the business for Phase Matched coaxial cable assemblies. 

 

Applications

  • Semiconductor test
  • Instrumentation
  • Military/Aerospace
  • Communications
 

Available Phase Matching Styles

  • Absolute Matching - Matching to a customer defined length.
  • Relative Matching - Matching assemblies relative to one another.
  • Delay-Matched in Pairs – Measured and selected from a large group of assemblies, then selected and labeled accordingly.
  • Delay-Matched to a standard – All cables matched to a standard β€œGolden sample”.
  • Delay Offset Matching – One or more cables are provided with a delay or offset.
 

All delay match values are specified in the actual time delay value, which is usually in picoseconds.  We have found that stating the match in terms of time greatly increases match consistency as well as match clarity.  Three (3) styles of phase matches may be performed: 

  • bsolute value tolerance: Β± 5 ps
  • Relative (typically pair): ≀ Β±1 ps
  • Lot match (several cables to many assemblies) please contact the factory for your specific needs.

Note: On long assemblies, typically > .4 Meters, stability of electrical length may become more dependent on cable type and length, please consult the factory with your specific requirements. 

 

Available Cable Styles

  • Air Spaced PTFE
  • Semi Rigid
  • Flexible PTFE, Flexible polyethylene foam, as well as other styles of flexible cables with various other dielectrics.
  • Corrugated, polyethylene foam and other styles available.
