RF rotary joint HRD080-2-SMA-4.5-12

HRD080-2-SMA-4.5-12 RF rotary joints are designed according to the skin effect of high frequency signals and the structure of coaxial cable. Support single or multi-channels to transfer DC~18GHz RF signals, also can be integrated electric and other signals. HF rotary joint high frequency signal use 50Ω characteristic impedance RF coaxial structure.
