Stable Electrical Characteristics and Low Attenuation

The CFT240 coaxial cable integrates a silver-plated copper inner conductor (0.50 mm) and LD-PTFE dielectric (1.38 mm) to achieve uniform impedance and excellent signal propagation (81 % velocity). It maintains phase stability within ±3° @ 18 GHz and ±5° @ 26.5 GHz, with amplitude stability ≤ ±0.1 dB @ 18 GHz. Its attenuation is as low as 0.637 dB/m @ 1 GHz and 5.93 dB/m @ 67 GHz, ensuring precise, low-loss transmission. The wide operating temperature range (–55 °C to +165 °C) guarantees dependable performance under thermal stress. For advanced setups requiring even greater amplitude precision and mechanical protection, see the enhanced CFT240A47 – Low-Loss & Phase-Stable Precision Test Coaxial Cable with armored construction and ±0.05 dB amplitude stability up to 67 GHz.

Durable FEP Jacket and High Shielding Efficiency

Encased in a 2.40 mm FEP jacket, the CFT240 test cable offers outstanding flexibility, chemical resistance, and wear protection. Dual silver-plated copper shielding layers ensure > 90 dB electromagnetic suppression for clean and consistent signal transmission. Its 12 mm single-bend and 24 mm repeated-bend radii make it ideal for frequent handling in precision laboratories.
