EconoFlex Ø4.57 mm (.180 inch), FEP Jacket and PTFE Braided cover, 50Ω, DC-40GHz

50 Ohm EternalPhase Coaxial Cable | FEP Jacket | EPTFE Dielectric

The ROSNOL EP0457 R-Test EternalPhase coaxial cable is engineered for high-frequency RF and microwave systems up to 40 GHz. It features a solid silver-plated copper (SPC) inner conductor, expanded PTFE dielectric, and dual silver-plated copper shielding layers. The cable is jacketed with FEP and reinforced with PTFE binder and braided PTFE cover, with an overall diameter of Ø4.57 mm [Ø0.180 in]. Minimum static bend radius is 19.05 mm [0.750 in], and the cable weighs 32.74 g/m.

Electrical performance includes 78.74 pF/m capacitance, 84% signal velocity, 3.94 ns/m signal delay, and insulation resistance ≥ 1×10⁸ MΩ/m. Shielding effectiveness reaches ≥ 100 dB up to 18 GHz, with a maximum operating voltage of 1.9 kVrms. Phase stability vs bending is ±5.0° typical / ±9.5° max, amplitude stability is ±0.05 dB typical / ±0.10 dB max, and phase stability vs temperature is <4°/m/GHz (−55°C to +125°C). Attenuation ranges from 0.36 dB/m (0.11 dB/ft) at 1 GHz to 2.46 dB/m (0.75 dB/ft) at 40 GHz. Max CW power is 500 W at 1 GHz and 75 W at 40 GHz.
