Phase-Stable 26.5GHz Ultra Flexible Precision Test Coaxial Cable with PUR Jacket – Model CFT500S

Flexible Low-Loss Cable for Portable and High-End RF Testing Applications

The CFT500S low-loss & phase-stable precision test coaxial cable offers the same electrical performance as the CFT500 but features a more flexible PUR outer jacket for portable and dynamic measurement setups. Operating up to 26.5 GHz with a 50 Ω impedance, it delivers consistent amplitude and phase stability under frequent motion. Fully REACH and RoHS compliant, the CFT500S combines mechanical flexibility with excellent signal integrity for laboratory and field applications. Explore the CFT Series – Low-Loss & Phase-Stable Precision Test Cables for other variants.

Consistent Electrical Performance and Low Attenuation

The CFT500S coaxial cable uses a multi-stranded silver-plated copper inner conductor (1.44 mm) and LD-PTFE dielectric (3.80 mm), achieving velocity of propagation of 82 %. It maintains amplitude stability ≤ ±0.1 dB @ 18 GHz and phase deviation ≤ ±3° @ 18 GHz / ±5° @ 26.5 GHz. Its attenuation curve is identical to the CFT500 series, ensuring uniform performance across all frequency points. For higher mechanical resistance and extended bending life, consider the CFT500A76 – Low-Loss & Phase-Stable Precision Test Coaxial Cable with armored protection.

Flexible PUR Jacket and Enhanced Mechanical Handling

Encased in a 5.90 mm PUR jacket, the CFT500S test cable offers superior bendability and impact resistance compared to fluoropolymer jackets. It provides a comfortable handling feel and improved traction on benchtop surfaces for daily operation. With a 25 mm single-bend and 50 mm repeated-bend radius, it is ideal for portable instrumentation or field testing. Browse the Precision Test Coaxial Cable Series for related flexible designs.

Applications Requiring Maximum Flexibility and Signal Integrity

The CFT500S low-loss coaxial cable is optimized for bench testing, network analysis, and diagnostic measurements in dynamic laboratory settings. Its high voltage rating (2000 V DC) and attenuation of 0.27 dB/m @ 1 GHz ensure accurate transmission under repetitive movement.
