Description
50 Ohm R-Test AccuStability Cable | TPU/FEP Jacket | LD PTFE Dielectric
The ROSNOL AS26B R-Test AccuStability cable is a precision-engineered 50 Ohm coaxial cable optimized for RF and microwave systems up to 26.5 GHz. It incorporates a 19-strand silver-plated copper (SPC) wire inner conductor, low-density PTFE dielectric, and dual silver-plated copper shielding layers. The cable is protected by a triple-layer jacket of FEP, TPU, and braided fiber, with an overall diameter of Ø7.30 mm [Ø0.287 in]. Minimum static bend radius is 9.65 mm [0.380 in].Electrical performance includes 86.0 pF/m capacitance, 80% signal velocity, 4.30 ns/m signal delay, and insulation resistance ≥ 1×10⁸ MΩ/m. Shielding effectiveness is ≥ 100 dB up to 18 GHz, with a withstand voltage of 1.9 kVrms. Phase stability vs bending is ±3.0° typical / ±6.5° max, and amplitude stability is ±0.10 dB typical / ±0.20 dB max. Attenuation ranges from 0.26 dB/m (0.08 dB/ft) at 1 GHz to 1.47 dB/m (0.45 dB/ft) at 26.5 GHz. Max CW power is 248 W at 10 GHz.
