40 GHz Heavy-Duty RF Precision Test Cable T42
P/N: T42
- For 40 GHz RF module testing
- 4.20 mm OD supports durable routing
- Bend-resistant structure for test durability
- Low VSWR supports signal integrity
- Blue FEP jacket protects test links
Engineering Note
The T42 is a 40 GHz heavy-duty RF precision test cable designed for high-frequency module testing, EMC laboratory environments, system-level test benches, and complex RF chassis interconnections where bend resistance, signal integrity, and durable routing are key selection factors. Its construction uses a silver-plated copper inner conductor, low density PTFE dielectric, silver-plated copper strip inner shield, low density PTFE interlayer, silver-plated copper wire braiding, and a blue FEP jacket. The cable supports reliable test routing while providing 81% velocity of propagation, >90 dB shielding effectiveness, 500 V.DC dielectric withstand voltage, and operation up to 40 GHz.
