67 GHz Integrated Armored RF Precision Test Cable T26KB
P/N: T26KB
- For protected 67 GHz test paths
- Integrated armor improves cable protection
- 20,000-cycle bending life for handling
- Multi-layer shielding supports signal integrity
- ±7° phase stability under movement
Engineering Note
The T26KB is a 67 GHz integrated armored RF precision test cable designed for protected high-frequency measurement paths, dense microwave laboratory routing, aerospace and defense test environments, and shielded microwave interconnects where mechanical durability and signal stability are both required. Its one-piece armored construction combines low density PTFE dielectric, silver-plated strip and wire shielding, aluminum foil and PI middle layers, reinforced winding and braiding layers, PTFE tape wrapping, and a purple-black PTFE braided outer protective layer. The cable supports demanding 67 GHz test routing with VSWR ≤1.30 @67 GHz, 20,000-cycle repeated bending life, ±7° mechanical phase stability, and ±0.15 dB amplitude stability.
