ConductRF has expanded the availability of its TUFF-FLEX
VNATM Test Cable family, a ruggedized line of precision RF test cable assemblies engineered for Vector Network Analyzer measurements through 40 GHz in demanding laboratory, engineering, and production test environments.
TUFF-FLEX VNA is one of three specialized product families within ConductRF’s growing True VNA RF Test Cable platform. Rather than designing a single test cable for every VNA application, ConductRF has developed three complementary cable architectures to meet the mechanical and electrical demands engineers face during precision RF measurement.
TUFF-FLEX VNATM emphasizes ruggedness and durability through 40 GHz. HI-FLEX VNATM emphasizes maneuverability and electrical stability during frequent cable movement through 70 GHz. APEX VNATM extends the platform into precision millimeter-wave measurements through 120 GHz.
When the Test Cable Has to Take the Abuse
VNA measurements depend upon the electrical and phase stability of the complete measurement path. In high-use test environments, however, the test cable is also a mechanical component that may be repeatedly handled, routed, flexed, connected, and disconnected throughout its service life.
TUFF-FLEX VNA cables were developed specifically for applications where the physical environment demands a more rugged solution. The assemblies combine precision RF performance with reinforced mechanical construction designed to withstand frequent handling, torsional forces, bending, and crushing. A stainless-steel spiral conduit armor protects the internal cable structure against excessive bending and mechanical damage, helping preserve the integrity of the test interconnect over repeated use.
This makes TUFF-FLEX particularly well suited for high-volume engineering laboratories, automated test systems, production test stations, and other RF and microwave measurement environments where cables can experience much greater mechanical stress than during occasional bench-top use.
Precision Performance Through 40 GHz
Standard TUFF-FLEX VNA configurations support frequencies through 40 GHz with 50-ohm impedance and connector interfaces including SMA, Type-N, TNC, 3.5 mm and 2.92 mm (K) configurations.
Depending on the selected cable and configuration, TUFF-FLEX assemblies provide crush resistance up to 1,050 lb/in., shielding effectiveness greater than 100 dB, and mating life up to 5,000 cycles.
The result is a test cable designed not simply to survive a demanding test environment, but to provide the electrical consistency required of the measurement interconnect operating within it.
Choosing the Right True VNA Cable
TUFF-FLEX is deliberately not positioned as the universal answer for every VNA application. Where engineers frequently reposition DUTs or manipulate cables during tuning and characterization, ConductRF offers HI-FLEX VNATM, a more maneuverable, lightly armored solution designed to minimize flex force while supporting precision measurements through 70 GHz.
For advanced millimeter-wave measurements, APEX VNATM extends the True VNA platform through 120 GHz using precision 1.0 mm interfaces and a flexible construction optimized for ultra-high-frequency measurement environments.
