Non-Magnetic RF Cable Assemblies

SV Microwave’s latest addition to its Non-Magnetic product family introduces high-performance cable assemblies engineered for magnetically sensitive environments. These compact 6" assemblies pair trusted SMA and SMPM interfaces with Ø.047" or Ø.085" flexible cables to deliver low-loss, high-frequency performance in a ready-to-use format. Ideal for applications in quantum computing, test and measurement, and defense systems, they maintain a maximum magnetic susceptibility of 10⁻⁵ with no field distortion. Supporting frequencies up to 40 GHz, these assemblies offer reliable signal integrity in environments where magnetic interference cannot be tolerated.
