High Performance RF Jumper Cables

Copper-corrugated jumper cable assemblies that feature unique connectors, solid center conductor cables and soldered inner and outer conductors
High Performance RF Jumper Cables Today's mobile communications systems demand very low intermodulation (IM) characteristics due to the crowded frequency spectrum used by these services. As a result, components that have not traditionally been known as IM contributors have become IM sources to consider. RF cables and their associated...
