High-Power, Ultra-Low-Loss Coaxial Cable for Stable RF Testing<\/h2>\n

The CFS740 ultra-low-loss precision test coaxial cable is designed for engineers requiring maximum power handling, phase stability, and low signal attenuation in professional RF and microwave testing. With a 50 \u03a9 impedance and operating frequency up to 18 GHz, it delivers excellent electrical performance and repeatability in calibration and signal integrity applications. Fully REACH and RoHS compliant, it meets the highest industry standards for quality and environmental safety.<\/p>\n

Superior Electrical Performance and Stability<\/h3>\n

The CFS740 coaxial cable features a solid silver-plated copper inner conductor paired with an LD-PTFE dielectric, ensuring minimal signal loss and outstanding impedance uniformity. It maintains phase deviation within \u00b1 2\u00b0 @ 10 GHz and \u00b1 3\u00b0 @ 18 GHz, while amplitude variation stays below \u00b1 0.1 dB @ 18 GHz. Attenuation remains exceptionally low \u2014 just 0.158 dB\/m @ 1 GHz and 0.685 dB\/m @ 18 GHz \u2014 enabling long cable runs with minimal insertion loss. Temperature-related phase drift is controlled under 750 PPM from \u201355 \u00b0C to +85 \u00b0C, guaranteeing repeatable precision across environmental changes.<\/p>\n

Robust Construction and High Voltage Endurance<\/h3>\n

Encased in a 7.40 mm PFA jacket, the CFS740 cable delivers excellent flexibility, abrasion resistance, and mechanical durability for high-demand testing environments. Its dual silver-plated copper shielding provides > 90 dB of electromagnetic protection, ensuring clean signal transmission even in high-interference conditions. With a 2500 VDC voltage rating, 37 mm single-bend radius, and 74 mm repeated-bend radius, it combines strength, electrical insulation, and handling comfort for precision measurement setups. Weighing 125 g\/m, it is ideal for both stationary and semi-flexible installations.<\/p>\n

Applications Requiring Low Attenuation and High Power Handling<\/h3>\n

The CFS740 ultra-low-loss coaxial cable is particularly suited for vector network analyzer (VNA) calibration, radar and satellite testing, 5 G component evaluation, and other high-power RF measurement systems where stability and signal integrity are essential.
