UTiFLEX® Flexible Cable Assemblies

The ultimate in flexible performance

For any application, from high-performance flexible interconnects for microwave systems to rugged everyday test leads, CarlisleIT UTiFLEX® flexible microwave cable assemblies provide unsurpassed performance.

All UTiFLEX assemblies are constructed using a low or ultra-low-density PTFE dielectric coupled with fully shielded outer conductors, which together offer excellent loss characteristics, outstanding phase stability and superb flexibility compared to standard flexible cables—all without sacrificing mechanical integrity.

CarlisleIT also understands that the most reliable microwave cable assembly requires not only the best microwave cable but also fully integrated connectors. That’s why we design and manufacture our own line of high-performance microwave connectors specifically for UTiFLEX cable—using a team of dedicated engineers and the most sophisticated design tools to optimize the electrical and mechanical integrity of the connector as part of a complete cable assembly.

UTiFLEX cable assemblies come in several variants to meet your specific application needs:

  • Miniature
  • Low-loss
  • Ultra-low-loss
  • MKR Ruggedized
  • External Armor
  • Ultralight


General purpose microwave cables designed to offer superior electrical performance in the smallest possible package for fixed installations. These cables provide an affordable alternative for systems that cannot tolerate the lower performance of RG cable assemblies or the cumbersome design consideration required for semi-rigid cable assemblies.


The most versatile microwave cable family offered by CarlisleIT. These cables have outstanding mechanical durability without sacrificing insertion loss, phase stability or VSWR (return loss). Low-Loss cables are readily available, moderately priced and suitable for a wide range of applications ranging from test leads to military systems.


Provide extremely low insertion loss and optimized electrical stability to meet the most demanding system requirements. Mechanically sized to common frequency bands (18 GHz, 26.5 Ghz, 32 GHz, and 40 GHz), these assemblies utilize an ultra-low-density PTFE dielectric that ensures unbeatable phase and insertion loss stability over both temperature and bending extremes. For phased arrays or any application requiring electrical repeatability, choose Ultra-low-loss UTiFLEX.

MKR Ruggedized

MKR represents the best in CarlisleIT technology. Using ultra-low loss UTiFLEX microwave cable as a base, MKR adds ultra-low-loss highly flexible and abrasive resistant ruggedness. The resulting integrated product becomes an ideal choice for test labs or any testing environment requiring excellent mechanical strength and long-term reliability. The MKR test cables have passed strenuous lifetime qualification testing to ensure long-term reliability.

External Armor

Most UTiFLEX assembly types listed above (except the MKR) are available with additional armoring options. External armor increases the cable assembly diameter, but can also significantly extend the life of the cable assembly especially in highly aggressive environments.
