Description
50 Ohm Multi Purpose R-Test Cable | FEP Jacket | Low-Density PTFE Dielectric
The MP420A is a high-performance RF/microwave test cable designed for frequencies up to 40 GHz. It features a solid silver-plated copper conductor and low-density PTFE dielectric for superior signal integrity. Dual shielding with silver-plated copper foil and braid ensures screening effectiveness of ≥100 dB up to 18 GHz. The cable diameter is 4.20 mm (0.165 inch), with a minimum bending radius of 10.0 mm (0.394 inch). Weight is 43.2 g/m, and the cable withstands over 5,000 flexures. Operating temperature ranges from -55°C to +165°C, and the cable is RoHS compliant.Electrical specifications include 50 Ω impedance, 86.0 pF/m capacitance, and 80% velocity factor. Phase stability is ±5° typical and ±9.5° max, while amplitude stability is ±0.10 dB typical and ±0.20 dB max under bending. Typical attenuation values are 0.73 dB/m (0.22 dB/ft) at 3 GHz, 1.86 dB/m (0.57 dB/ft) at 18 GHz, and 2.85 dB/m (0.87 dB/ft) at 40 GHz. Maximum CW power handling ranges from 375 W at 3 GHz to 103 W at 40 GHz.
