High-Power, Low-Loss Coaxial Cable for Stable RF and Microwave Measurements<\/h2>\n

The CFS550 ultra-low-loss precision test coaxial cable is designed for professional RF measurement systems requiring high power handling, low attenuation, and exceptional phase stability. With a 50 \u03a9 impedance and operating frequency up to 18 GHz, it ensures reliable, repeatable results for metrology, network analysis, and signal validation. Fully REACH and RoHS compliant, it delivers both performance precision and environmental responsibility for long-term laboratory and production use.<\/p>\n

Exceptional Electrical Performance for Accurate Testing<\/h3>\n

The CFS550 coaxial cable features a solid silver-plated copper inner conductor and LD-PTFE dielectric, achieving ultra-low attenuation\u2014just 0.223 dB\/m @ 1 GHz and 0.961 dB\/m @ 18 GHz. Its phase stability remains within \u00b1 2\u00b0 @ 10 GHz and \u00b1 3\u00b0 @ 18 GHz, while amplitude variation is limited to \u2264 \u00b1 0.1 dB @ 18 GHz. The cable maintains < 750 PPM phase drift from \u201355 \u00b0C to +85 \u00b0C, ensuring repeatable measurement results in both controlled and varying thermal conditions. With an 83 % velocity of propagation, it provides excellent signal accuracy across the full frequency range.<\/p>\n

Durable Structure and Shielding Integrity<\/h3>\n

Encased in a 5.60 mm PFA jacket, the CFS550 cable offers mechanical strength, flexibility, and outstanding chemical and thermal resistance up to +165 \u00b0C. Dual silver-plated copper shields achieve > 90 dB shielding effectiveness, minimizing EMI and maintaining clean signal transmission. The cable withstands 2000 VDC and supports a 28 mm single-bend radius \/ 56 mm repeated-bend radius, enabling robust performance during repeated connection cycles. Weighing 93 g\/m, it balances strength and flexibility for demanding high-power RF environments.<\/p>\n

Applications Requiring High Power and Repeatable Phase Stability<\/h3>\n

The CFS550 ultra-low-loss coaxial cable is ideal for high-power test setups, radar verification, VNA calibration, and microwave system integration requiring minimal insertion loss and consistent phase response. Its combination of mechanical durability, shielding efficiency, and stable thermal performance makes it suitable for both laboratory and industrial test systems.
