Product Description
Core Advantages
-
Wide Temperature Range: -55°C to +150°C operational capability for extreme environments.
-
Lower Attenuation:Foam PTFE contains more air, reducing dielectric loss—critical for long cable runs and high-frequency applications.
-
Higher Velocity of Propagation:Signals travel faster (80–85% vs. 70% for solid PTFE), reducing latency in time-sensitive systems.
-
Lighter Weight:Lower density dielectric reduces overall cable weight—ideal for aerospace and portable equipment.
-
Improved Flexibility:Foam structure is inherently more pliable, requiring lower bending force.
- Exceptional Phase Stability: Mechanical phase and amplitude stability under flexure, critical for phased array and high-precision applications.
-
Cost-Effective:Foam dielectrics can offer performance approaching air dielectric at lower cost.
Application Scenarios
- Wireless Communications: Higher velocity reduces latency; low loss improves system efficiency.
- Test & Measurement: Reduced need for power compensation in extended test setups.
- Aerospace: Lightweight construction reduces payload; flexible routing aids installation.
- PIM Test Cables: High shielding effectiveness ensures accurate passive intermodulation measurements.Foam-Flex 047
Why to Choose Our Low Loss Coaxial Cable?
Engineers select Foam Flex 047 low loss coaxial cable when they need a flexible microwave cable that combines the low‑loss benefits of a foamed PTFE dielectric with the mechanical ruggedness required for demanding environments. Its 77% velocity of propagation and 25.9 pF/ft capacitance outperform solid‑PTFE designs, while the proven dual‑layer composite shielding guarantees >100 dB isolation up to 60 GHz. With a compact 1.48 mm outer diameter, tight bend radii, and compatibility with standard semi‑rigid connectors, Foam Flex 047 delivers semi‑rigid electrical performance in a truly flexible, easy‑to‑route package – ideal for aerospace, test & measurement, wireless backhaul, and millimeter‑wave systems.
