Stable Electrical Characteristics and Low Attenuation

The CFT420 coaxial cable features a multi-stranded silver-plated copper inner conductor (1.02 mm) with a low-density PTFE dielectric (2.70 mm), delivering 81 % velocity of propagation and outstanding impedance uniformity. It maintains amplitude stability ≤ ±0.1 dB @ 18 GHz and phase deviation within ±3° @ 18 GHz and ±5° @ 26.5 GHz. Attenuation remains low at 0.394 dB/m @ 1 GHz and 2.64 dB/m @ 40 GHz. For applications requiring greater amplitude precision and mechanical reinforcement, consider the armored CFT420A70 – Low-Loss & Phase-Stable Precision Test Coaxial Cable offering improved long-term durability and stability.

Durable FEP Jacket and High Shielding Effectiveness

Encased in a 4.20 mm FEP jacket, the CFT420 test cable provides excellent thermal and chemical resistance for extended operational life. Dual silver-plated copper shielding layers ensure > 90 dB EMI suppression, maintaining clean and repeatable signal transmission even under environmental stress. Its 21 mm single-bend and 42 mm repeated-bend radii allow consistent flexibility in laboratory or production test setups.
