Reliable Electrical Design for General RF Applications

The CFE800 cable features a 2.30 mm silver-plated copper inner conductor and a low-density PTFE dielectric for low insertion loss and stable impedance. Dual shielding layers — self-adhesive aluminum foil and silver-plated copper braid — provide > 90 dB EMI suppression, while the FEP jacket ensures flexibility and chemical resistance. Attenuation values remain as low as 0.151 dB/m @ 1 GHz and 0.763 dB/m @ 18 GHz, with a velocity of propagation of 76% for accurate phase control.

Durable, Cost-Efficient, and Mechanically Stable

With an outer diameter of 8.10 mm, single-bend radius of 40 mm, and repeated-bend radius of 81 mm, the CFE800 low-loss coaxial cable maintains excellent durability and mechanical reliability. It supports up to 2 kV DC voltage and operates from –55 °C to +125 °C, making it suitable for laboratory, communication, and general RF setups where long-term stability and cost efficiency are key.
