40 GHz Low-Loss Flexible RF Cable L23
P/N: L23
- Ultra-compact cable for dense RF routing
- Low-loss path for microwave interconnections
- Blue FEP jacket for flexible installation
- Low PIM performance for cleaner signals
- Supports high-density 40 GHz applications
Engineering Note
The L23 is a 40 GHz low-loss flexible RF coaxial cable designed for compact microwave routing, internal RF interconnections, and precision device testing where low attenuation, controlled shielding, and small cable diameter are required. Its 2.33 mm blue FEP jacket, LD PTFE dielectric, silver-plated copper strip inner shield, and silver-plated copper wire braid outer shield support reliable high-frequency signal transmission in dense RF assemblies. The cable combines DC–40 GHz operating capability, -155 dBc low PIM performance, and a compact mechanical profile for high-density microwave applications.
