40 GHz Economy RF Precision Test Cable J40
P/N: J40
- For high-volume ATE test systems
- PUR jacket resists production-line wear
- Linear phase supports fast compensation
- Flexible construction for frequent handling
- Rated to 40 GHz for test links
Engineering Note
The J40 is a 40 GHz economy precision test cable designed for automated test equipment, high-volume production lines, and repeatable microwave component verification. Its construction uses a silver-plated copper inner conductor, low density PTFE dielectric, silver-plated copper strip inner shield, PFA interlayer, silver-plated copper wire braiding, and a blue PUR wear-resistant jacket. The cable supports frequent test-system handling while providing 83% velocity of propagation, >90 dB shielding effectiveness, and ±0.3°/GHz mechanical stationary phase for cost-effective 40 GHz test links.
