For many years, designers all over the world have relied on Carlisle Interconnect Technologies’ (CarlisleIT) UTiFLEX® Flexible Microwave Cable Assemblies for the most demanding defense, space, and testing applications. When a microwave assembly must deliver consistent reliable performance over time, UTiFLEX has become the industry choice.

Now, CarlisleIT offers UTiPHASE™, which combines every traditional feature of UTiFLEX with a thermally phase-stable proprietary dielectric that eliminates the PTFE “knee”. UTiPHASE also leverages the same cable assembly terminations and proven connector families that have made UTiFLEX famous, thus saving money, validation schedules, and lead-times.

Applications:

• Commercial and military phased-array radars

• Synthetic aperture radars

• Thermal test sets

• Any RF/microwave system operating at or near room temperature

• Commercial and military aerospace SATCOM and TCAS (Traffic Collision Avoidance System)

Bends to Your Application. Stands Up to Everything Else.

UTiFLEX® microwave cable assemblies are constructed  using a low or ultra-low-density PTFE dielectric coupled with fully shielded outer conductors and a unique connector attachment that withstands mechanical and thermal stresses far better than standard connectors. The result: Excellent loss characteristics, outstanding phase stability, and superb flexibility compared to standard flexible cables — all without sacrificing mechanical integrity.

Available variants:

Miniature

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.

Low-Loss

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.

Ultra-Low-Loss

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.

Ultra Light

Optimized for spaceflight applications, these cables provide the lightest weight, lowest insertion loss, and best radiation resistance in a flexible cable construction. They features an ARACON® outer shield, an ultra-low-density PTFE dielectric, and a DuPont Tefzel® jacket. If required, cable assemblies are manufactured in a Class 10,000 clean room by certified solder technicians.

TVAC

Thermal vacuum testing is a risk mitigation strategy utilized in some hi-rel applications, notably space equipment such as satellites. CarlisleIT TVAC Test Assemblies are thermal vacuum compatible for use in TVAC chambers. These assemblies utilize high-performance, Ultra-Low-Loss UTiFLEX Cable and are produced to exacting space-grade standards utilizing low-outgassing materials and vented connectors.
