Ultra Low Loss 70 GHz Precision Test Coaxial Cable with PTFE Jacket – Model CFS150

Ultra-Low-Loss Precision Cable for High-Stability RF Testing

The CFS150 ultra-low-loss precision test coaxial cable is developed for RF and microwave engineers seeking superior electrical repeatability and phase stability. Operating up to 50 GHz with a 50 Ω impedance, it provides low insertion loss and consistent phase control for precision testing, calibration, and signal integrity verification. Fully REACH and RoHS compliant, it embodies Mechanc’s commitment to quality, precision, and sustainability in high-frequency measurement systems.

Consistent Electrical Performance for Reliable Measurements

The CFS150 coaxial cable integrates a solid silver-plated copper inner conductor and LD-PTFE dielectric to achieve stable impedance and ultra-low attenuation—only 0.715 dB/m @ 18 GHz and 1.220 dB/m @ 40 GHz. Phase deviation remains within ±2° @ 10 GHz and ±3° @ 18 GHz, while amplitude variation stays below ±0.1 dB @ 18 GHz. With a thermal phase drift below 750 PPM between –55 °C and +85 °C, the CFS150 ensures highly repeatable measurements and long-term stability across temperature cycles.

Durable Construction and High Shielding Efficiency

Encased in a 1.50 mm PFA jacket, the CFS150 cable offers excellent thermal resistance, chemical durability, and mechanical flexibility. Dual silver-plated copper shields achieve > 90 dB EMI suppression, maintaining clean, low-noise signal transmission even under dynamic motion. The cable’s balanced geometry minimizes impedance variation during handling, while its robust outer protection extends service life in demanding test environments.

Available Variants for Specific Test Requirements

In addition to the standard version, the CFS150 Series includes several optimized variants:

• CFS150U — increased mechanical flexibility for setups where cables are frequently repositioned.
• CFS150UE — extended-frequency model offering precision performance up to 67 GHz for wideband metrology and 5 G calibration.

These complementary versions provide tailored solutions for various laboratory, production, and high-frequency testing needs within Mechanc’s precision cable portfolio.

Applications Requiring High-Frequency Precision and Phase Stability

The CFS150 ultra-low-loss coaxial cable is ideal for vector network analyzer (VNA) calibration, radar testing, and 5 G signal verification applications demanding consistent phase and amplitude response. Its solid-core design and PFA jacket ensure reliable performance under frequent use, making it a dependable choice for both laboratory and production-grade RF measurement setups.
