Description
50 Ohm UltraFlex Coaxial Cable | PUR Jacket | LD PTFE Dielectric
The ROSNOL UF0550 UltraFlex cable is designed for high-power RF/microwave applications up to 18 GHz. It features a silver-plated copper inner conductor, low-density PTFE dielectric, and dual silver-plated copper shielding layers. The cable is jacketed with PUR and has an overall diameter of Ø8.00 mm [Ø0.315 in]. Static bend radius is 40 mm [1.575 in], dynamic bend radius is 80 mm [3.150 in], with a weight of 118 g/m.Electrical specifications include 78.72 pF/m capacitance, 83% signal velocity, 4.00 ns/m signal delay, and shielding effectiveness ≥ 90 dB up to 18 GHz. Attenuation ranges from 0.19 dB/m (0.06 dB/ft) at 1 GHz to 1.02 dB/m (0.31 dB/ft) at 18 GHz. Maximum CW power is 418 W at 1 GHz and 75 W at 18 GHz.
