Emerson Connectivity Solutions / Johnson SMA Hand-Formable Cable Assembly

Johnson Connectivity Solutions SMA Hand Formable Cable Assembly is a fixed-length cable assembly and an excellent alternative to semi-rigid cables, which are more costly and less flexible during early design stages. Ideal for RF/Microwave applications, this SMA cable effectively eliminates additional tooling charges. When RF interference is not an option, these cables provide 100% shielded cable coverage assuring an outstanding VSWR and low insertion loss of up to 18GHz.
