Ultra Low Loss 40 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 40 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 7.604 dB/m @ 40 GHz. Phase stability and amplitude stability remain excellent. With excellent thermal phase stability, 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 FEP 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.

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 FEP jacket ensure reliable performance under frequent use, making it a dependable choice for both laboratory and production-grade RF measurement setups.
