Details About RF coaxial cable-NTD
NTD Cable Structure
1 . Silver-plated copper center conductor
2 . ND-PTFE dielectric
3 . Seamless copper tube
No suffix – bare copper
TM – Tri-alloy plated
TP – Tin plated
NTD Cable Low Loss Semi-Rigid Coaxial Cable
NTD series semi-rigid cable provides lower loss, lighter weight, higher power handling capacity, and less temperature-related phase change than competitor’s. It features a silver-plated copper center conductor, low-density PTFE dielectric instead of solid PTFE, and a solid copper tube outer conductor and uses the same solder-on connectors as standard semi-rigid cable. Typical applications include test setups, interconnection, and instrumentation. It is available for fast delivery as cable and OEM is welcome. There is no minimum order quantity requirement.
Features
- Low loss

- Plenty connector options
Typical Applications
- Aerospace
- Plate-to-plate connection
- Card interconnection
- Cabinet jumpers
- Airborne radar
- Missile systems
- Phased array radars
- Feed networks
- Instrumentation
