5. Applicable Environment and Working Conditions
RF coaxial cable refers to a cable with twoCoaxial Conductor, andConductorPlease provide the Chinese content to be translated.Shielding LayerCables sharing the same axis.
Physical insulation material for RF coaxial cablesExpanded PolyethyleneInsulated copper wire conductor composition: externally to the inner layer of insulating material is another layer of annular conductor, the outer conductor (organizing shielding layer), which is formed from copper strips, welded, and crimped; or it uses an aluminum tube structure; or a woven structure. Then, the entire cable isPolyvinyl Chloride (PVC)The material sheath covers the components.
There are two common types of射频 coaxial cables:50ΩAnd75ΩOur RF coaxial cables.
Characteristic Impedance75ΩRF coaxial cables are commonly used forCATVWeb, hence the nameCATVCables, transmission bandwidth up to1GHzCommonly usedCATVCable transmission bandwidth:750MHz。
Characteristic Impedance50ΩRF coaxial cables are primarily used forBaseband SignalTransmission, transmission bandwidth of1～20MHz，
General characteristic impedance50ΩThe maximum transmission distance for the thin coaxial cable is:180Rice, Coaxial Cable in Rough Condition1000Grain.
