Description
50 Ohm UltraPhase Coaxial Cable | FEP Jacket | EPTFE Dielectric
The ROSNOL MPUL330A UltraPhase coaxial cable is engineered for high-frequency RF and microwave systems up to 50 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 has an overall diameter of Ø3.30 mm [Ø0.130 in]. Minimum bend radius is 6.4 mm [0.252 in], and the cable weighs 28 g/m.Electrical specifications include 78.7 pF/m capacitance, 83% signal velocity, 4.00 ns/m signal delay, and insulation resistance ≥ 1×10⁸ MΩ/m. Shielding effectiveness reaches ≥ 90 dB up to 18 GHz, with a maximum operating voltage of 1.9 kVrms. Phase stability vs bending is ±6.0° typical / ±11.8° max, and amplitude stability is ±0.05 dB typical / ±0.08 dB max.Typical attenuation ranges from 0.39 dB/m (0.12 dB/ft) at 1 GHz to 3.34 dB/m (1.02 dB/ft) at 50 GHz. Maximum CW power handling is 450 W at 1 GHz and 50 W at 50 GHz.
