Description
50 Ohm EconoFlex Coaxial Cable | FEP Jacket | PTFE Dielectric
The ROSNOL EF402 R-Test EconoFlex coaxial cable is designed for precision RF and microwave applications up to 26.5 GHz. It features a solid silver-plated copper clad steel wire (SPCW) inner conductor, PTFE dielectric, and dual silver-plated copper outer conductors. The cable is jacketed with FEP, with an overall diameter of Ø4.14 mm [Ø0.163 in]. Minimum bend radius is 20.3 mm [0.799 in], and the cable weighs 45 g/m.Electrical characteristics include 96.1 pF/m capacitance, 70% signal velocity, 4.72 ns/m signal delay, and insulation resistance ≥ 1×10⁸ MΩ/m. Shielding effectiveness reaches ≥ 110 dB, with a maximum operating voltage of 1.9 kVrms. Attenuation ranges from 0.28 dB/m (0.09 dB/ft) at 0.5 GHz to 2.66 dB/m (0.81 dB/ft) at 26.5 GHz. Maximum CW power handling is 527.5 W at 0.5 GHz and 72.5 W at 26.5 GHz.
