Professional Industry Advantages
-
Ultimate Shielding Effectiveness: By utilizing a seamless bare copper tube as the outer conductor, this cable provides a total electromagnetic seal (100 percent shielding). This eliminates any possibility of signal leakage or external interference, making it superior to any braided or wrapped coaxial alternatives.
-
Superior High-Frequency Fidelity: Specifically engineered for performance up to 10 Gigahertz. With an exceptionally low Voltage Standing Wave Ratio (VSWR) of 1.15, it ensures maximum energy transfer and prevents internal signal reflections in sensitive microwave circuits.
-
Precision Mechanical Stability: The semi-rigid nature of the copper tube allows the cable to be bent and formed into complex shapes during installation while maintaining that fixed geometry. This provides consistent electrical performance even under mechanical stress or vibration.
-
High-Purity PTFE Dielectric: The high-grade PTFE insulation ensures a low dielectric constant and stable performance across the entire thermal spectrum from -55 degrees Celsius to +125 degrees Celsius (-67 degrees Fahrenheit to +257 degrees Fahrenheit).
-
Compact Micro-miniature Profile: With an outside diameter of only 0.88 mm, this cable is ideal for ultra-high-density integration within RF modules where space is extremely restricted but signal integrity cannot be compromised.
