Multi Purpose Ultra Low Loss Ø4.22 mm (.166 inch) , FEP Jacket, 50Ω, DC-40GHz

50 Ohm Multi Purpose Ultra Low Loss Coaxial Cable | FEP Jacket | EPTFE Dielectric

The ROSNOL MPUL422A is a precision-engineered coaxial cable for RF systems up to 40 GHz. It features a solid silver-plated copper (SPC) center conductor, expanded PTFE dielectric, and dual silver-plated copper shielding layers. The cable is jacketed with FEP and has an overall diameter of Ø4.22 mm [Ø0.166 in]. Minimum bend radius is 12.7 mm [0.500 in].

Electrical specifications include 80.05 pF/m capacitance, 84% signal velocity, 3.9 ns/m signal delay, and insulation resistance ≥ 1×10⁸ MΩ/m. Shielding effectiveness reaches ≥ 90 dB up to 18 GHz and ≥ 80 dB up to 40 GHz. Phase stability vs bending is ±5.0° typical / ±9.5° max, and amplitude stability is ±0.1 dB typical / ±0.2 dB max. Attenuation ranges from 0.331 dB/m (0.101 dB/ft) at 1 GHz to 2.099 dB/m (0.640 dB/ft) at 40 GHz. Maximum CW power is 500 W at 1 GHz and 75 W at 40 GHz.
